What offends you?

Many people are offended by a lot of things. For different reasons. Some aren’t offended by much at all. Tell me your story, in the meanwhile, I’ll tell you mine.

I’d like to say that virtually nothing offends me, but that isn’t true. I’m like the most non patriotic person ever, and I don’t think that things like cultures and countries should separate mankind as it often seems to do. I won’t base my judgement of someone on account of where they come from, or where they live.
Yet, I totally hate it when someone insults or makes fun of my country. Not because of what is said of it, but rather because when people do this, they usually seem to use that to personally insult me. I think that’s pretty low, seeing as it’s not relevant to me as a person, at least not in my mind. I mean just insult me individually, not wherever I’m from. (But I guess, whatever works right?)
Of course, everyone makes fun of France, hell I do it too, and I don’t mean that THAT offends me, but rather when it’s used against me, as I’ve explained. I don’t know if it’s making any sense, but yeah.
I know this guy who totally hates the French, but we’re friends anyway. He really likes seeing me angry for some reason though, and basically he blames me for World War II, or when I react or whatever he’ll always say just how ’‘French’’ everything I say or do is. Anyways I haven’t spoken to him forever, and don’t plan on doing as such if I can help it. Plenty of people have found that using my roots or heritage against me pisses me off, or, ’‘offends’’ me, per se. Or maybe not, maybe it actually does offend me, even if it’s not directed at it, and I just don’t wanna admit it. Anyways.

So what offends you? Whatever it is. Mentalities, moral aspects, or lacks thereof, practises, swear words, behaviours, whatever, and explain why, if you can. This question is not meant to instruct or deviate people away from what offends them, it isn’t meant to start fights or anything, but just to get your peeve off your chest, at least for a bit.
