there is a nuanced difference between transphobia and not wanting to discuss topics that cause arguments in a school
It’s still transphobia, the only reason it’s viewed as a political topic is because of transphobia. It’s pretty cowardly to say we should avoid talking about gender/trans issues just because it makes people uncomfortable, and might cause arguments. Trans people exist, but you’re arguement kinda says to me “They aren’t worth the trouble, id rather sideline them to avoid disagreements.”.
Abortion is a rough comparison, it’s a heavy topic and I think it would probably be inappropriate for more reasons than just being a “Political” topic.
