I do not think that I have far-right views, I do not follow their "party" line however, for example I am pro-free speech for everyone.

I was accused twice by antifa people of being fascist myself. Once because I expressed my pro-archiving/anti-copyright views and another time when someone accused my friend (who is an actual anti-fascist that organises non-violent anti-fascist events in real life) of being a fascist because he does not agree with their violent policies and I went to defend him - in neither case they explained why they think that I am a fascist and I had no prior interaction with these people.

Regarding antagonism, in general people reply only when they have something to add or when they disagree with a post. If they have nothing to add but agree then they just upvote instead. I can't guarantee that this is the case here however.

Nicely demonstrating ops point; if someone points out the behaviour of accusing all who disagree with you of being nazis it's unwise to immediately accuse said person of sharing views with Nazi like groups .

I feel like I told him he had a "Chaplin-like moustache" and then your comment paraphrased my comment as "Hitler-like moustache." They may be similar moustaches, but the latter would neither be what I actually wrote, nor meant.
