Not really. I see you're from feddit.de, so you must also know about the esoteric scene slipping into alt-right communities with the pandemic. I'm sure there are plenty of vegans with pretty conservative views.
This post is at least one example, even if it's not a German esoteric.
if u think of being left bing against forms of hierarchies, then abolishing hierarchies that benefit beings that are not even human is the most left thing you can go. just because there are people that don't follow their own morals to all regards, doesn't mean it ain't right.
