Gaslighting is when you tell someone that what they see with their own eyes and hear with their own ears isn't real and you're doing it in order to discredit their judgement and make them doubt themselves. That is what you're doing with your casual denial that this post is straight up hateful towards all men.
You can do your mental gymnastics and deny this all you want, but one has to be blind and stupid to not understand the purpose of this post as being divisive and hateful towards men.
As a woman, I do not approve of this type of bs, especially not in a group that is supposedly against spreading hatred.
