I remember printing out the Gentoo installation manual in the compsci lab way back in 2004. It was my first Linux distro and have fond memories of tinkering around on it. I remember leaving it a few years later for a cool new distro that was on the rise called Ubuntu. I still think portage is one of the better approaches to package management though.
I think overall I associate more people on the left being vegan than the right; however, anecdotally I know more vegans that are conservative/right leaning. I don’t know why that is other than maybe it being a fairly well off area with hippie roots.
