I didn't say that. I said you compared them. You did so again in this comment, again putting them on the same level as taboo discussion subjects for children, which is just plain wrong. The fact that people of the same gender can love each other is not hard to understand, it's really quite simple to explain, but your last comment attempted to make it sound difficult to explain, seemingly to justify speaking in hushed tones about it or not at all if children are nearby, as if you were talking about their deceased parent. But it's an easy-to-understand, neutral subject, so your point is invalid.
And really? One kid tells another kid that his dad is an architect, the second kid asks the teacher to explain what the first kid's dad does. And the teacher says "No, I can't talk about anyone's parents." That's what you're going with?
This isn't necessarily about a student's parents anyway. That's just one example of where a child might be triggered to ask about it. Kids are curious, they will ask, and with this new legislation teachers will avoid it as if the kid asked about death. And when something gets treated as if it's taboo, it becomes taboo.
