Kinkshaming may be against the rules but I love to be a hater. Disclaimer, I don't genuinely think anyone into any of these things is irredeemable, and I can genuinely understand why someone might be into them. Regardless,this is more about how kinks can and do affect the real world. I just use my blacklist and I hope you all do the same. Im just taking an opportunity to gripe with how kink affects how you see others, NOT coming at you personally.
Loli/shota as well as the whole infantalism/baby thing. I've seen people progress from ddlg to straight up talking about peoples past assaults and traumas and jacking off to it (trauma kink)
Incest is shockingly common everywhere as a kink, which I absolutely loathe. It's something I have nightmares about and while I can blacklist it on r34, other sites simply don't give me the opportunity or people don't tag their swaths of nightmare inducing incest porn. People tend to forget its a very insidious type of abuse because of how much porn of incest there is, in my exerience.
And finally what ive coined as "Bigotry play" as a catch all term. Describes orientation play as you stated but also raceplay, detrans, and anything derogatory that could come from a place of bigotry (which is sort of vague Ill have to admit) such as seeing disabled people as cute and helpless, trans people as a fetish thing, etc.
The last ones are the big 3 (p-do, n-cro, zoophilia) but thats not a hot take at all and most people on this site would agree with me on that last one.
And another edit just in case, I understand you cant control your kinks but I am on my knees crying and begging and pleading for you to look at how it affects other people. I also do this with myself, I'm no saint, hell I'm even into some fucked up shit myself, I just do my best to keep it from affecting those who I love and care for.
