Earlier today a vegan made a post with a white supremacist dog whistle by satirizing a person who's people "have been eating dog for thousands of years". Another Indigenous person and I did our best to call out the white supremacist nature of the discussion, so the poster later edited the title to specifically reference European people, which may have been well intentioned but only served to gaslight us by making it look like we were over-reacting and looking to be offended.
I came here for the leftism, and stayed for the Trans Rights. I'm a 2-spirit, native leftist. I have myriad reasons why I may or may not choose or even have the choice of veganism and any moralizing or condescension that comes from white vegans is an extension of over 500 years of an imposition of an alien value system which is profoundly disconnected from this land and the plants and animals which are our blood relations.
The difference is animals are not part of the leftist movement (save for a handful of based riot dogs). If you're homophobic, racist, transphobic, etc. inviting you into the leftist movement weakens it by excluding others. Someone who eats burgers isn't excluding anyone from the leftist movement and therefore not an impediment to Leftism.
