I think he seems to have the problem a lot of ED newfags tend to share, that is, they don;t know why everyone hated furries in the first place and what made them so insufferable. They don't know about April Fur's day and they don't lurk.
Many of them will say its "degenerate." Whether it really is or not is kind of up in the air, but let's face it - you're a board where you're one click away from seeing two girls, each with multiple ten-foot, throbbing erections, sucking feces coming out of said erections. They either don't know or try to ignore the fact that Lola in a bikini is far less degenerate than shitting dick nipples.
No, we hated furries because they were so man obnoxious an cringe-inducing. 4chan in 2004 was undergoing a war for its soul, fought between weebs and furfags. The furries were trying to make the place their own, and they brought their drama, their in-fighting, their ridiculous jargon, and their persecution complex with them. Hopefully you know the story form here: Moot makes a /fur/ board, traps them all there and permabans all of them.
In the meantime, most of what yo find on /co/ is just anons being anons- if it passes the Harkness test, it's good. Doesn't matter fi it's furry, xeno, what-the-fuck-ever. No one here is posting fursonas, no one here is promoting their FA.
But of course, everyone needs an axe to grind.
