mrs terra the bottom line is that you've always been a massive friend and considering that you can't decide what gender you are, i think you're the one that's trying to compensate for something(or lack thereof)
This honestly should not be brought up, unless this was a drama about how he's doing a kitty-style sockpuppeting where he legit has an alter ego where he pretends to be a girl.
Now, Mr. Bones was a richard sucking friend when he came and he's probably gonna be a richard sucking friend when he leaves, but attacking him on a personal level enables people to dogpile you for stuff you've done in the past.
Attacking a baseless post with personal insults is fine, but all of Mr. Bone's posts have a surface you can slash at. Use that to actually get a hold onto the people who would be willing to support you while also making an argument that only makes the other person look stupid when they say stuff about your past that's largely irrelevant.
