At some point in your early childhood, a well-meaning parent or teacher probably sat you down and shared what they believed to be the simple facts of life—that the world was made of boys and girls. Boys have penises and girls have vaginas, they said, and they made you think it was really that simple. We see the same sentiment reiterated in political debates over “bathroom bills” and job protection acts being contested in state and local governments all across the country. Certain politicians and concerned citizens are genuinely confused to hear LGBTQ advocates and allies inform them that both gender and sex are more nuanced than they know. 

Sadly, to this day, one of the most commonly Googled questions cis/hetero people ask about the trans community is: “Is being trans a mental illness or a reaction to trauma?” For folks coming to terms with their identity and trying to break free from the confines that previously held them back, this misconception can be deeply disheartening and cruel. The best way to combat ignorance and myths about gender is with education and information. Here are some main points to put gender fluidity and trans identity in context.

Even the APA Knows Better

Gender identity issues have been studied in the Western World since the mid-1800s. In the 1950s, the first gender confirmation surgeries and medical interventions were performed on a select few individuals, and awareness from the psychological community increased. It wasn’t until 1980 that the Diagnostic and Statistical Manual of Mental Disorders (DSM) put a label on gender identity incongruence in patients. They listed it as “Gender Identity Disorder” and added subcategories to this diagnosis. This lead many in the general public to believe that being transgender was a problematic and deviant behavior, a misconception still currently being propagated by many politicians. The latest DSM categorizes a range of gender identity and presentation experiences under the title of “Gender Dysphoria,” dysphoria meaning a state of unease or dissatisfaction. This transition illustrates the psychiatric community’s evolution in its understanding of gender identity issues not as illness, but as states of anguish for those unable to identify and present as their true gender.

To understand what this all means, we need to dig deeper into the historical and cultural factors that play into this debate. First, we must understand that the terms “sex” and “gender” are not interchangeable, nor are they the same. Sex is a biological characteristic based on chromosomal factors and sex characteristics such as genitals. Gender is a social construct and refers to how an individual navigates the world through identity (pronouns, names, etc.), how we dress and our mannerisms (feminine, masculine), and how we see ourselves. Often, these two get mixed up, resulting in the misconception that our body parts decide our gender.

Chromosomes Don’t Like Binaries

Some folks (heterosexual and LGB) continue to argue that there shouldn’t be a difference between a person’s sex and gender—that, in fact, they must be one and the same. The problem with this argument is twofold. 1. There are dozens of variations in chromosomes. 2. The idea of only two genders is a modern-day creation. While it is most common for people to be born with either an XX pair of chromosomes (female) or XY (male), it has been well-documented that many other clear variations (XXX, XXY, XYY, XXYY) and slighter variations of the X and Y combinations are more common than many people understand. What this means is, even if sex decided our gender, there are far more than two sexes.

The Gender Binary is a Modern Creation

From a cultural and historical perspective, the gender binary is a relatively new concept. However, because of Judeo-Christian colonization, we think this binary has existed since the dawn of time. When missionaries landed around the globe and saw that a majority of indigenous cultures had three or more genders, they sought to extinguish these beliefs and practices. Now, more and more indigenous activists are speaking up and reclaiming the terms once used for their gender fluid tribal members, also known as two-spirit people. The term “two-spirit” refers to the belief that LGBTQ people have two spirits living inside them, an experience that allows them to view the world holistically and to be closer to the divine. The Navajo call them nádleehí. In Siberia, the Chukchi are tribal shaman whose third gender identity designates them as spiritual leaders within their community. In the Maori cultures of New Zealand, they are the wakawahine. In the Democratic Republic of the Congo, they are called the bangala and are said to possess unique abilities to solve crimes, as they see the world from multiple angles. We see historical evidence of third and gender fluid people on every continent who were not only tolerated, but celebrated by their communities. 

Beyond the biological, cultural, and historical facts that gender is a spectrum, there are also benefits to embracing gender fluidity. Numerous studies have shown how strict gender roles can become toxic—from male entitlement over female bodies, to unequal pay, to physical stress stemming from unevenly distributed household labor, to the disbelief of male victims of sexual assault, the problems are seemingly endless. The modern Western idea that gender has to fit into constricting and separate boxes benefits few and harms many. Some fear this means LGBTQ advocates are pushing for a world where no one can have a gender identity and everyone is forced to be androgynous. This is simply not true. LGBTQ activists are simply advocating for personal and societal freedom and growth, which has the potential to benefit everyone.

When a person comes out as transgender, gender fluid, or genderqueer, they are following in a lineage that was and is sacred in many societies around the world. Because of biological and cross-cultural increased awareness, more and more people feel free to live openly and to stand up for their rights as people whose identity is both mentally sound and authentic. There has not suddenly been an increase in transgender folks, either—simply an increase in people who feel safe being themselves. The more we, as societies and communities, come to understand this idea, the safer—both physically and emotionally—the world can be for our trans siblings and people of all gender identities and expressions.
