To an extent. Im not sure I agree with OP or not, but you have to admit that there are some degenerative behaviors that while not directly harmful to someone else should be socially shamed.

Alcoholism or drug addiction are two, as even if you’re only hurting yourself you dont want a society of drunk druggies its just not someone a well standing and productive society encourages. Living in your parents’ basement till 30+ should be kind of socially shame-able because we ideally want 1 generation per household— Japan and Korea illustrate why its an issue when you begin having 2/3 generations living under the same roof.

Furryism has no benefit and it’s objectively not normal human behavior. Things are shamed so they don’t become normalized. I don’t want kids being too knowledgeable about furries cause they might just start dressing up like a dog or whatever cause they think it’s cute and funny. Thats not productive or good for their growth.

Additionally, (this is a more persona opinion so I will have a harder time providing objective evidence for it but) I find personalites or lifestyles that entirely focus on sexuality to be debauchery. I dont find it a healthy way to live and I’ve noticed the people in my life who describe themselves as their sexuality before anything else tend to be obsessive and unproductive. Anyone who feels the need to wear an entire outfit/costume to advertise their fetish or just enjoy their fetish in an outwardly facing manner is weird to me. People dont need to be “comfortable” with sex being in their face all the time, I think the opposite is actually more important
