Lemmy’s userbase is currently skewed very left wing, many people on the left are vegan or vegetarian or at least care about climate change enough to see reduction in meat consumption as a necessity to fixing it.

So it shouldn’t be too much of a surprise that you see more anti-meat discourse.

Disclaimer: I eat meat

I’m confused by this and totally open for evidence that proves otherwise, but literally everyone I know who is vegetarian or vegan is a bit more or…insanely more on the conservative side.

I don’t know any liberal vegetarian or vegans.

Vegan here. I don’t know any conservative vegans, except for a single YouTuber. From an anti-oppression perspective, being on the right doesn’t really make sense for veganism. The right will perpetually define the taking of conscious life as personal choice as if a choice itself is morally relevant. Anyway, perhaps you live in an area with lots of repubs and neolibs?
