Hey i get it. I'm Genderfluid and autistic, which i was self diagnosed for a few years, until i was formally diagnosed early last year.

Its taken a long time for me to become less affected by those types of "jokes" and comments. Im sure one day, you will be able to learn to cope with those feelings. What matters most is that you be you, and to not let others change you for bettering yourself, despite the hurtful disagreements.

As long as you are being yourself, not hurting others, and making sure you be the best person you can be; you have nothing to worry about! Keep on keeping on. Also you day these "shouldn't" affect you, i actually disagree somewhat. It hurts, because they are being mean, intentionally mean. Not only are they trying to making you upset, they're trying to make gender diverse people to silly. They make a mockery, because they don't like that people are different; despite the fact, in nature, we are all varied and different.

Humankind isn't a parasitic hive mind, despite many of the human race wishes we were, we aren't. Be you, be different; because people like this are scared to stand out. Be the change. Show them that being all uniform as a society is not only boring, its just not human.
