Well it gets fatiguing to debate all the time, especially when some people are just trolling. But you can ask questions like what do you do for protein, B12, iron, etc. without debating. What are some staples that vegans eat, is it easy to make vegan food, how expensive is vegan food, what does a balanced vegan meal look like, what are some recipes, etc. Even asking can a person thrive on a vegan diet through all stages of life and you'll probably be given an article or recommended to watch Game Changers.

I think they want to stop the antagonistic people, especially if all they want to do is say: it is only natural to eat meat/we evolved to eat meat, humans have dominion over animals, animals don't have feelings, vegans are just being overemotional aka only logical people eat meat, it is ok to kill animals, killing animals in factory farms is ok because it is efficient, there isn't enough land to grow vegan food for everyone, etc. Just shit that's been responded to a million times and at this point seems bad faith since it's been debunked before. Maybe they could have a sticky or wiki about these common arguments, idk I am not a mod.

It also matters what your tone is and that can be the difference between someone asking questions in good faith vs someone doing an antagonistic debate. But yeah at this point vegans do not need to question their values or opinions when it comes to their diet and lifestyle. You cannot convince a vegan it is ok to kill an animal for food but you might be able to convince a non-vegan it is wrong to kill an animal for food. Anyway that was just my thoughts on it.
