Somehow your view of leftists is wrong.
A) Maybe you talk about the most left of the left, maybe 5% of the population. Yes, those might be those gender study idiots.
B) If you consider anybody left of center, maybe about 50% of the population, you should be able to find out that they don't have much to do with what you describe above.
Maybe you noticed that some of the left, especially the once with the big mouth, claim that anybody in the right is a nazi and a racist and all that.
Are you a nazi and a racist? I guess not. Are you right of the center? I guess yes.
There is not just radical left and radical right.
