As is pedophilia, adultery, incest and whole host of other moral degeneracies. Any government that would promote school children celebrating such has no concern for children at all. Rather it is an attempt to normalize something they know deep inside is fundamentally wrong.
Pedophilia and incest are crimes (when applying to minors). Adultery is bad, but not criminal. It’s a matter of the heart; and although I condemn it and for me it’d be the cause of cessation of a friendship in theory, I can only say: it occurs, it’s bad, and well, end of story.
Homosexuality is not a crime and it happens between consenting adults. Who am I to judge it?
Sometimes, being humble and modest is the best policy.
