Is Twilight appropriate for a 12-year-old?

Any genuine interaction risks this, as the stalker is in love with their idea of the person, not the actual person. Behavioral or personality traits, even interests that diverge from that super compelling idea of the person may create revulsion or hatred, up to and including violence, in people who are obsessed with someone.

Which is how many real-life stalkers see themselves. They’re so in love, they can’t help themselves. If anything happened to their beloved, they’d give up anything, take any kind of beating to protect them.

No. The relationship modelling is horrific, and children are especially vulnerable to false messages on this front.

Edward and Bella’s relationship starts because Edward stalks Bella. He watches her in her sleep and he followers her around; him following her is revealed when he jumps out to save her, the implication being that it’s good he stalked her. We’re supposed to see this behavior as him loving her, caring about her, and being willing and able to protect her.

Rejecting the stalker is even more perilous. This is the harshest possible challenge to their romantic obsession, and they will respond by trying to prove themselves—that is, by intensifying their stalking—or by immediately devaluing the beloved and lashing out, often violently.

It’s dangerous no matter how you slice it, life-threateningly dangerous, and encouraging young people to see behavior this toxic as romantic and a sign of love is socioculturally poisonous. We risk people’s lives by teaching them these things.

How do I come out as queer to my best friend in a funny and stupid way?

Don’t teach them that stalking is romantic. Just don’t.
