Tropes that became problematic

[u/KalzK]

The Persistent Suitor: A guy who is after the girl and just wont take no for an answer. Nowadays we just call stalking and harassment, but it used to be romantic. Example: The Notebook (2004), Noah asks Allie out while she's on a date with another man. She refuses, but he threatens to let go and fall unless she agrees to go out with him.

Comedic Woman On Man Violence: Mostly seen in anime, recently it has decreased a lot but years back every show had a woman hitting a guy and showed it as funny. Example: Toradora!, where the quintessential tsundere, Taiga, beats up the MC regularly.

Kid Bags Adult Baddie: I remember a few of these, sometimes it was to show how cool and awesome a kid was because an adult woman fell for him, now it's just seen as problematic shit. Example: Blank Check, the woman likes the kid and kisses him telling him to look for her in 10 years.
