Some do, many don't. A fursuit is a costume, as a cosplayer in fandoms do, and I guarantee there are cosplayers that have sex in their costumes.
Knowing quite a few fursuiters there's less of them that want to have sex in suit because it's hot as fuck, makes you a lot more clumsy, and those suits are expensive as hell as they're custom made.
Thing is, it isn't "Just vote", it's being absolutely active every step of the way. Dunno what your territory is but my state we're having an absolute route of the ultra-right wing going for every local position with the Republicans national conference funding them, the Dems have considered the entire state a lost cause.
So kinda, yea, it is a pull yourself up by the bootstraps, and anyone else who you can pull up as well because we're sure as hell not getting help from the top, but it's either that or sit on our fucking hands and go "whelp". Remember, whether you like her or not, AOC primaried the supposed "2nd in command" Democrat. If you don't like the establishment, you root it out from the bottom.
