You are supposed to throw fascists from helicopters.
In line with the original top comment, why don't you publicly declare that you you'll treat discrimination/slander of whites/men/conservatives/scientists/free-speech-advocates on this platform just as harshly as you would any other group instead of asking me to send you a dozen emails per day.
FWIW, I hate the left and the right movements in equal strides, the left want me to feel terrible for being born a straight white male in a western post-colonial society, the right want the poor and under-priviliged to suffer and horde things like medical care.
Understanding that there is a grey-scale and that ideologies are not absolute is the only way to proceed in my opinion. Being polarised only turns into fighting because nobodies view gets represented properly instead both sides put up strawmen.
Ironically to me, your second paragraph illustrates why your first paragraph matters: As someone belonging firmly on "the left" your description does not fit me at all, at least not in my view.
The problem, then, when someone wants to go to extremes in treating anyone over their perceived ideology is defining what it means to belong to or support said ideology sufficiently strongly to warrant that extreme action.
And hence I do agree with your last paragraph.
Twitter is rife with absolute venom if you even suggest a term such as "mansplaining" is sexist.
