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.
I didn’t grow up using it, but now as an adult I love it. I use it at least once a week with friends, family, and co-workers with intended offensive score of one or two. I have a friend that sends me pictures of clowns late at night when she knows I’m home alone. That’s pretty deserving of a middle finger or two.
