If you don't want to be referred to, then don't post. If you don't offer a way to speak to you one will be provided, as you exist and therefore owe taxes.
I feel like you're stirring the pot, fair enough. Pots are meant to be stirred. The "their" as a pronoun example is weak, it suggest poor language skills.
If you are genuine that its uncomfortable to say "they" instead of he or she, harden up. Have a think about how uncomfortable someone would have to be to ask you to do that.
You've got to deal with a lot of people in this world. Furries that want to bang animals, crooked politicians who fly to Paedo island with Epstein, but you're devoting your mental space to pronouns.
