You can see this as hate speech against women or the community saying in it's own fucked up way "we don't care and you shouldn't announce these labels to us"
This was more of the case when they first started doing it. More recently its devolved into actually being hate speech in accordance to poe's law. You really only see it on /b/ though.
It's an honest interpretation on a lot of boards. Of course this is a trend, not the rule. I can't speak for everyone. This wouldn't be true on places like /pol/ or /b/
Generous interpretation
