No, it is not those things you display, it is very likely YOU personally they don’t like. Seriously.
That’s a plausible assumption; however, they all occurred when I was parked in places I don’t normally visit. I take it you’ve never had a liberal scream at you or hurl insults at you - things like “bigot”, “Nazi”, “fascist”, etc. - when you offered a viewpoint that countered their dogmatic perspective on anything? I’ve found that liberals are rarely more than a couple talking points deep and don’t appreciate the value of logic.
Furthermore, and being completely honest, I haven’t really cared whether communists/Marxists/progressives/socialists (but I repeat myself) “like” me for a long time. I used to just walk away, shake my head and avoid the discussion, but no longer do that.
