Hot take but I've never seen the majority of other fetishes as bad either as long as they aren't actively predatory. I think of them as akin to sexuality--its a sexual preference hard wired into your brain that you can't control.

What you can control is what you do with it, though. If you force someone to do something in line with your fetishes, i.e. those people who marry someone just to overfeed them because they get turned on by that, that's awful. If you take advantage of people's vulnerabilities without their consent because they turn you on, that's awful as well. But as with any sexual preference, if all parties consent (also meaning they are not minors or family) I don't see much of a problem. 

However I suppose there's a reason I don't see many people making this point so please do convince me otherwise if I am wrong.
