Vegans are strictly not into animal stuff right? vegetarians have varying lines they will self establish which may include eggs and dairy and whatever the fuck is in gummy bears etc etc etc. It's the one niche part of the animal where it pretty much is going to landfill or getting fed to the chickens otherwise.
Why should vegetarians be responsible for the waste from people eating meat? Surely the onus there should be on the meat eaters to eat the rest of the animals they choose to eat.
Ps the stuff is gelatin and there's a huge range of gelatin free gummys available these days.
