Why not take a little time out of your day to examine your assumptions? You say "we have to keep saying something until its true", which isn't relevant when we are already discussing the truth. And holy shit kid, sex isn't gender. This isn’t a concept incompatible with the science of biology. You have the power to not be a stupid pile of shit. I can't tell you what to do but generally people don't like to fuck around with shit.
Great question. Read between the lines. They have done the following:
Called me a "transphobic cunt" in response to me saying that transphobes are cunts.
Doubled down by suggesting that I am projecting when I tell them I am not transphobic when I assumed they misread my comment.
Claimed that statements like "trans women are women. Trans men are men" are "things we need to keep repeating until they become true" suggesting they aren't already true. Said the reason for this is because "we are fighting biology".
Otherwise revealed themselves to be a transphobic cunt.
So, upon realizing they are just a transphobic troll, I spoke to them in the words of their people and called them a rotten pile of shit. I later lightened it up a bit and explained that while they are free to be who they want, most people don't like hanging out with shit. I said this to be nice and try to inspire change, but it only goes as far as these folks are willing to accept, which isn't much, as they are intolerant of science and the reality of the world around them.
