I've never met a vegan in real life who is annoying (about veganism. Maybe about other things...) Most of them it even takes a while to find out they're vegan. Several bosses I only found out because a team lunch. Several others I only found out because I befriended them at work and after months of talking to them it finally came up one way or another. Never even be criticized by them, and likewise, I've never criticized them (in general I have very few issues with veganism. Maybe I disagree with them on honey bees, and not even sure that's all vegans. Oh, and perhaps the belief that one cannot love any animal if they eat meat, but its not a topic i wish to agrue so I dont bother engaging anyway.)

Online you may have someone being more abolitionist or mutant about veganism, but even them it's hardly an issue unless you go into vegan spaces or are commenting about certain things like that dolphin shooting, and even then it's not really mostly on the level of whataboutism and being really extreme and preachy.
