I'm just making a generalization based on experience. I don't care what anyone eats, they can eat Soylent Green if they've sourced it legally.

Just in my experience vegans always have to announce it with trumpets that they are indeed a vegan and make a big deal out of it. If going out with friends, just order whatever meets the diet and be quiet about it. I don't announce if I order a burger with a side of vegetables that I did that because I do in fact eat meat and that I don't eat french fries.

Again, that's based on my experience. Perhaps there's a bunch of quiet vegans that do what I'm suggesting but I suppose they don't draw notice.
