↩ Ivan "I would never be gay" is exactly what I would say if I was a closeted gay person. Your beliefs are severely skewed, warped around your flawed environment likely due to bad parenting or lack thereof, and quite frankly invalid. Gender isn't assigned at birth, this shows you don't have a good understanding of the difference between sex and gender which is a very basic concept, I'm not too sure how far you've gotten in your education. The terms they and them have been around, documented and used since the 1300s - likely earlier. It is ironic you see sex and gender as rather contemporary topics, before christ, the greeks would fuck men all the time. As depicted through their art and culture, there was no stigma around this. Considering you're used to only two pronouns, the weight of a third pronoun (they/them) must be a large task for your ragworm-sized brain to interpret. Your final remark left me split on what you believe so I'll ignore it.
Hope this helps!
