My concern with questions on this basis is that there's a strong danger of them just being opinion. There's no governing body of vegetarianism and veganism that decides what does and doesn't count, it's a personal choice on what a veg*n considers acceptable.
For example this question
It's now closed as opinion based, because the answer is really just "it depends on what a person thinks". It could possibly be reformed into something more specific asking about how many worms might be harmed by farming, but in this state it's not useful.
Similarly, one might want to ask "Can vegans eat honey?" but there's no real consensus on that. However one could fairly ask about whether honey bee farming has negative environmental effects, or if honey bees suffer in any way from being farmed.
What do people think? Should these questions be closed as opinion based, get a custom close reason or maybe have canonical question/s about the broad definitions of vegetarian, veganism and similar lifestyles?
