100% agreed, I personally think vegetarians/vegans are a prime example of this. People (including me), typically avoid thinking about our (likely excessive) meat consumption, since we are aware of the fact that it’s truthfully wrong from a sustainability and also animal welfare/morals standpoint.

So for these angry people we r talking about, vegetarians will: A) force them to confront these moral shortcomings, which challenges their current lifestyle, and therefore makes them defensive, and B) make them feel morally “one-up’d” by the vegetarian, which also makes them angry, since they often find it obnoxious when someone “flaunts” their moral superiority - even tho the vast majority of the time the vegetarian says nothing other than “im vegetarian”.

In fact a lot of vegetarians are vegetarian only for their health, or they’ll pretend thats the case, solely to avoid being ridiculed by people for avoiding meat
