It isn’t just an assumption. I’ve met a lot of people on this forum and community in general. The VAST majority are completely against AI. Even more so than me. Can’t even post a funny gif if it involves an AI image. (I don’t care when it’s used for memes or just messing around, and I openly stated that I did play and enjoy an AI game in one of my posts.)
I wouldn’t expect someone with an AI image as their profile picture to understand. It’s extremely unethical to use AI in its current form. There is no valid comparison to vore. Vore doesn’t harm anyone. AI does. The only people who defend the use of AI, not just opposing its outright ban, are a tiny but loud minority that usually just end up getting angry and leaving.
