You should know that you're presenting the exact kind of attitude that alienates people. The conversation you're now saying has no place for cis men never made any such distinction in the first place. That was something you created to be angry about.

If we discount the misogynistic roots of the comment you originally replied to, we would find a comment that was about the view misandrists have on men. This made no exception for cis or trans men, and in fact, would realistically include them equally, since I'm pretty sure a misandrist wouldn't like a trans man any more than a cis man.

The point is, the aspect of this conversation that you're angry about and gatekeeping over originated with you.

But I'm a cis man, EVERYTHING is about me! /s
