I myself am more "traditional" than the tumblr people, I actually despise them and the SJW "non binaries" for giving trans people such a musty reputation, but I still find it strange that y'all think an innate psychological gender doesn't exist while simultaneously putting such an emphasis on gender roles.
Of course I believe that if a body can have a birth sex then a brain can have a birth gender. And due to the countless anomalies that children can be born with I find it no surprise that some of us are born with a brain gender that doesn't match our physical sex.
And also I wanted to say that I don't understand how liking a trans woman makes a man gay or bisexual. Why do cisgender people boil others down to genitals? A woman isn't a vagina and a man isn't a penis. A man can like penis while not liking men. A man can enjoy penis while still desiring a woman.
The existence of a mental birth gender and the possibility of babies being created with a birth gender that does not match their birth sex makes absolute sense to me, while thinking people need to have certain characteristics due to their birth sex and can't change it doesn't make sense to me. I don't understand why I and so many other women have had to suffer so much for being born physically male, why everything we say is rejected and we're told we're mentally ill, and why people are downright mean to us.
I started my transition at 14 years old and I had to buy my hormones offline due to what I consider parental and medical neglect. I've experienced so much pain and hurt and fear and heartbreak over the last 8 years and why? I don't know, I don't understand. It's gotten better but I hate knowing how many teenage girls are experiencing the pain I had to experience and maybe worse, and for no reason that I can fathom.
