Thing is, gen alpha's parents grew up with weird shit themselves, edgy stuff that pushed the boundaries of what is acceptable. MTV and Comedy Central productions for a lot of people, stuff like Beavis & Butthead, Jackass, South Park, and then the 2000's internet of Newgrounds productions. Especially South Park I think desensitized the millennial generation, to the point where there's nothing that really weirds us (well, me) out.
I never watched skibidi toilet or much gen alpha stuff, but I'm not shocked by it or anything. I just think it's weird and surreal, but nothing worse than e.g. Salad Fingers.
