Sometimes, we eat during meetings - or rather, they eat. I can confirm from the food served and their willingness to eat it that very few, if any of them, are vegan. I always decline food but don't say why, but eventually, I'm sure someone's going to ask.
And that's the moment I've been dreading. I've been on Hexbear since it first went online. I've seen, firsthand, how much non-vegans - even the communists here, who have better politics than 99% of the people I know - fucking hate us. I'd go so far as to say at this point that I'd be more comfortable telling an average lib I'm vegan than I would a communist. At least the lib will probably just see it as a strange personal choice rather than accusing me of being a fifth columnist.
In all likelihood they won't give a shit and will even try to accommodate you. They might do a bad job it for various reasons like not knowing how to cook something which isn't borger, or going to the store and buying a pack of impossible borgers because they think what vegans want is a venture capital funded simulacrum of animal cruelty. What you should do is angle yourself into the position of organization grillmaster, and teach them what good food tastes like.
