Social skills as used by men to get into sexual or romantic relationships with women do not consist entirely of things I would describe with "negative feminist language".

Do you mean social skills which are used (almost) exclusively for these purposes? Most social skills are general, and in fact are more important to have than narrowly applicable ones.

this thought is dangerous because it can lead to evil behaviors, up to and including rape.

More to the point, this thought is wrong. (I agree that it feels unpleasant, but I don't know how much it actually leads to such behavior vs. being used to explain it afterwards.)
