Coming back to this thread, I really don't like any "dere" types...........
I like character alignment categories, sure, but dere-types tend to limit creativity a lot.
Most yanderes are the same - stupidly homicidal cartoony mockeries of people with mental illnesses.... Not to mention how they try to make sociopathic behaviour look sexy... And as someone who has been manipulated by a love interest it really isn't.
There are occasional characters that are referred to as yanderes that are actually interesting, but I tend to not call those characters "yandere" in the same way because I see the word "yandere" as an insult for a character. It kind of implies that the character is nothing outside of that trope
I have one crazy in love character in my current comic, but she's not completely 2-dimensional like that. She is willing to do crazy and dangerous things to win over the person she likes, but she doesn't have a maniacal laugh. She doesn't do typical stalkery things. She isn't traditionally attractive. She's obsessed, sure, but she's tragic for it rather than being sexualised and romanticised. There's no lean towards seeing her as desirable, because I didn't want to follow a trope. She's just a stalker. She's scary, and not in the way a weeaboo would find sexy - genuinely scary.
There are more than enough stories romanticising people who are downright terrible romantic partners. It needs to stop. "Yanderes" suck, but you can make a character "crazy in love" without making them lame.
