I'm totally ok with people disagreeing with me, on whatever issue, about religion, philsophy and politics, I don't mind at all, quite the opossite, finding that more interesting, I would have an issue with opinions that could affect a person's credibility and reputation, if they are unfounded, and if I like the person affected or if it's me.
Ad nauseum, the form of repeating the same word or phrase, all over and shouting it, ignoring any argument and evidence, is quite annoying, e.g. "Liar", "he did it", "No no no.."
Appeal to force, is also annoying, although it could be necessary sometimes, depending on the situation.
Sometimes I find, not annoying, but funny with those who believe to actually know and be the judge of truth, their "truth". I sometimes see this as a dangerous thing, with distrust, when they are activists and have some power.
