EDIT: since by “meat shill” that is referring to the types of people unironically touting a meat-only diet with zero vegetables as the healthiest thing in the world despite all the evidence to the country
Also to correct misinformation in the comments, estrogen and testosterone themselves are vegan. Most HRT injections on the market are fully vegan as well
They never said that there aren’t trans vegans, they said that they have witnessed a subset of vegans spouting transphobia online with claims from those same vegans that hormone therapies weren’t vegan. They did not make a claim one way or the other about it themself.
