I agree that's what the episode was saying, but the Tragic Queer forbidden love trope is an old one and far too often the only story we get. In this show, they also went with Evil Sexy Lesbians (and bisexuals). At least we were spared the other usual trope which is Dead Lesbians. Again, none of these tropes would be a problem if there were lots of other stories as well. But there weren't.
