My biggest gripe with vegan communities is that a lot of them have an “All or Nothing” mentality, going fully vegan is a luxury not everyone can afford, and yet I find mainly malice when trying to talk about reducing ones own reliance on meat and other animal products in online communities.
And veganism, if taken to the “no suffering of sentient beings” full extreme, forbids buying things (not just food) produced by slavery. And those things, especially electronics and clothes, are not financially viable for most to be bought without any slavery involved in any step whatsoever.
