Good Entry, although the bottom line shouldn't be that all feminism is bad and toxic, there are still some valid issues and moderate people. The problem are those fem-nazis or however you want to call them.
Yet I can to some degree understand, why there is such toxicity in femisim, anti-rascism movements or SWJ communities. If everyone has to fight for their life, they will try to get an advantage every way possible and over time this will result in civil unrest we see in all areas of soceity(i.E. politics, social media).
