Why do most ppl overlook furry yaoi?

I strongly believe furry yaoi shouldnt overlooked but why is it? Like shotacon, its between a minor and adult which is terribly wrong and when readers come out saying they read it or such many ppl rage on. Saying that you still shouldnt read those even if you seperate fantasy/reading from irl. However, i feel like same should go for furry yaoi. Its literally a human with an animal. They’re having sex, tongue kissing, would you imagine if a real human does that with their dog or sum, thats literally animal abuse.
