Probably easier just to ask what reforms you do support, or at least you think would be effective?
We could slaughter them in more pain free ways, but it doesnt’t change that they don’t consent to be killed. Thats sort of a non starter for vegans.
They already are supposed to have clean living conditions and there are penalties for animal abuse, they just are rarely reported and punished.
I think the problem I have with regulation is it rarely seems to work out when we do get regulations. They are written deceptively, and then aren’t enforced.
I suppose that doesnt mean good regulation is impossible but its part of my reluctance.
