Saw a gross comment get dumbed down to a "joke"

The guys are father and SON. Blood related people. And this person made a supposed "joke" that they should kiss (in a lover way, not father and son way). They started getting called out in the replies so they just dumbed it down and called it a joke instead of deleting the comments. Why are people on TikTok like this?? Just watch the mukbangs and don't comment your weird f3tish3s on a public comment section. It's gross and people there are trying to watch for the food. Also the kid is noticeably younger than the father, and the father has a wife. I really don't know where I can post this, but this is TikTok related and some post here are call out posts so.. spreading awareness. We shouldn't let these people be comfy.
