/co/ wasn't part of that given how the majority of /co/ stuff is about animal characters and many are purposefully made sexy. Also, many of the people shitpsoting about furries back then were furries themselves and a lot of the classic "yiff in hell" images were drawn by furry porn artists from /tg/. Speaking of /tg/, they were one of the most furry boards back in the early 2000s. And to top it off the "furry hate" meme was one moot stole from SA back in the day even though he and other weebs like the founding people of 4chan were lumped in the same category as furries and other such people by SA back then. And I know even more how much of a newfag you are too since /co/ had threads untouched by mods each day dedicated to different animal species only a few years ago.
Furries got replaced long ago has people reee at on 4chan. Only the /co/ mods care anymore.
