Curiosity:
vegans are not the same as vegetarians. Vegans are like the Neturei Karta of vegetarians… They’re totally looney.
My wife and one of my daughters are vegans, and comparing them to the NK is the worst kind of lashon hara, not to mention calling them “totally looney.” They mind their own business and they don’t spend time trying to convert anyone (including the rest of the family) towards their way of eating. Obviously, there are some vegans who are looney, but what you said is way over the line.
