Distrust of women, gender slurs, dehumanization of the other gender etc.

I do believe that they are needed, and that's because:

1. They serve as filtering mechanism. The people who are disgusted by the lingo never belonged there in the first place.
2. It's a closed backdoor against a form of "political correctness". It starts with "you can't say that", and ends up with the madness that is the current western official/political landscape.
3. It is a solution to Wahmen Ahre Wanderfall problem that a lot of guys subscribe to - evolutionary unfortunately. Idealism has dehumanized women far more than what TRP can ever hope to achieve. By dehumanizing the Idealistic version of females, we're actually putting them back on the map called "women are people too".
