After pestering my vegan friends with a bunch of questions about vegan people:

Me: How do vegans feel when you ask them a question, and then treat their answer as representative of all vegan people?

Him: That’s a difficult question to answer…

Me: Then how would you feel if I were to ask you a question, and then treat your answer as representative of all vegan people?

Him: I don’t think it would be accurate to extrapolate like that.

Me: Ok, then I will assume all vegans would also feel that it would not be safe to extrapolate like that.
