In an even more nuanced look at it, Stu Laurie, why should straight relationships be OK to talk about and celebrate among children, but not gay relationships?
If straight people can be talked about with respect to dating and relationships, and if nobody objects that that’s “sexual,” then why should gay relationships be inherently too sexual for kids?
Saying that we can’t talk to children about gay people because it’s not appropriate to talk to children about sex is an assertion built upon heteronormative assumptions that simply don’t hold up under anything but the most cursory examination.
By the way, it does get a little difficult definitionally to separate love and sex sometimes when the sexual and romantic spectra are examined independently.
But that’s a side issue.
The main one is that it isn’t necessary to talk to children about sex in order to talk to them about relationships, whether those relationships are same-sex or opposite-sex.
It’s all about equality.
