Anarchism

I don't know if Varyk's claim of your style of engagement is true, I haven't looked at your comment history, so I'll respond to what you've faced regardless of if you've attracted more disagreement than strictly needed.

Being an anarchist, and being super direct and upfront about your views, is going you get you some ire no matter where you go.

The reason is, generally speaking, you're looking through history and systems of power with a lens that makes the problems with those other systems quite glaring.

The people who have adopted those other systems and ideologies will have already accepted the cognitive dissonance that comes with them, and they're not going to take kindly to your nuanced opinion that makes them have to reevaluate their cognitive dissonance again. It's much easier to dismiss or attack you instead.

Now there are ways of softening your critiques and opinions to make them less liable to attract anger, such as adopting the Mr.Rogers style, but sometimes that can be too soft, depending on the context. You'll have to decide when that's appropriate for yourself.

Also, bear in mind that while sometimes your viewpoints and arguments will gather hatred no matter what you do, and it can seem hopeless to express your views, as though it does no good; there are many more neutral lurkers than there are people who engage with you directly, and you'll be having an outsized impact on that group just by having that counter arguement or viewpoint available for them to compare, which may unknowingly be changing minds for the better.
