My Opinion
I’ve been a bit confused why I see videos with that gesture censored, I feel like that rarely happened in the media I consumed a decade ago. However, I believe this “phenomenon” is older than TikTok and its weird censorship.
I’d place giving the finger at a high 2, low 3 on offensiveness, definitely nowhere near gesticulated sexual acts. You can give a child shit for using it, but the occasional finger is something I’d expect from even a teenager.
Careful you don’t get shot (assuming you live in the US). I’m not even joking. Road rage shootings are very much a thing.
Thankfully I live on the other side of the pond!
