Here's my take as a non vegan who has vegan friends. There are vegans, and there are vegans who make it their whole personality. A vegan friend once told me that he struggles to date fellow vegans because often they make it their whole personality and he'd rather have other hobbies and interests. 

Here's the thing, vegans do have the moral high-ground. But many of the confrontational ones don't understand that they won't convince anyone to their way of life through insults and anger. If you tell someone they're immoral, the immediate response is to dislike the person because most people believe that they're a good person.

I hate this whole moral high ground shit, sure they don't eat meat, but I'm sure they still use an I phone. This isn't just for veganism either, its literally anything people use to claim the high ground. Some people will pick one or two things that are convenient for them to support just so they can feel good inside while ignoring the numerous other evil companies they're giving their money to. 

I don't really care what anyone else does for the most part, but can we all stop pretending we're being good people by picking some cause to support, and finally accept that the way we live  in the western world inherently involves the exploitation of others less fortunate than us.
