I can easily accept that someone else thinks something that I disagree with, but have a button that's very easy to find when people start elevating themselves by belittling others en masse.
My attitude on that is so long as whatever they enjoy doing has no
major actual negative effects on me or others it's not my place to belittle the choices others make, even if I don't understand their reasoning. Note the term "actual effects", as in negatively impacting health, or having a high probability of causing injury, etc. If I just don't happen to like something which is otherwise harmless, I keep my mouth shut. For example, I'm not a fan of tattoos but it doesn't harm me in the least if someone else is.
It doesn't harm me either if someone prefers lanterns over flashlights, or vice versa. Nor do I care if a person likes incandescent flashlights instead of LED. Only a very small subset of choices are actually harmful to me, like inattentive/drunk/drugged driving/cycling. I reserve my ire for those things only.
My button is when people start trying to control my life by telling me how they
think I should be living. I had a former friend like that. That's the reason why he's a former friend. Literally every choice I made in my life, he belittled it, even stuff I did 40 years ago. "Oh, why didn't you get married?, Why didn't you have kids?, Why don't you date?, Why didn't you put more effort into your career?, Why don't you like my almost daily 2 or 3 hour phone calls?, Why don't you ever wear shorts?, Why don't you use a bike helmet?" Ugh. I'm getting aggravated just writing this, never mind when I went through it. Not one thing he ever bothered me about affected him personally. Well, maybe his desire to take up a lot more of my time than I wanted chatting about nonsense did, but that's his idea of friendship versus mine. If he wanted a friend like that, he should have stopped bothering with me when he saw I wasn't into constant, long phone calls.
