I’m vegan and the number of people who can’t figure out “no animal products” is astounding. I’m so tired of “no eggs? No dairy?” like yes bitch, I don’t fuck with animals.
There's always going to be a question as to where you draw the line. For example, is it okay to eat figs, even though they're pollinated by wasps that end up in them? Is it okay to eat plants grown using animal products as fertilizer? Is it okay to eat cultured meat that is many generations removed from a living animal, such that none of the material present now was part of the living animal? How about things in the animal kingdom, but outside the chordates? The ones you'd need a microscope to see? Is honey okay to eat?
There's also the issue that other people that call themselves vegan will disagree with you on what all counts.
It’s usually not that complex. If someone has a plate of chilaquiles with egg on it and I say I’m vegan I don’t think it’s hard to discern that I’m probably not going to eat it.
Egg is obvious if you know what the difference is between vegetarian and vegan in the first place, but I don't think you can expect most people to be able to cook vegan food, even if they're trying, and know the basic definition. I know enough non-obvious uses of animal products(like shellac on fruit), that I'd have no confidence in being able to avoid them all unless I grew everything myself.
How could I forget? It always blows people’s minds that I don’t eat fish, but before I was vegan I never liked fish anyway but no one had a problem with it then.
To be fair, the person you're responded to said "vegetarian" not "vegan." But yes, otherwise, it isn't rocket science. My vegan boys are big fans of seitan.
Don't forget salad. Outback is largely one of the worst if you're vegetarian unfortunately. Most steakhouses at least have a few vegetable sides and can make a meal out of them.
