We already rarely discuss politics, so would it be terrible to also discuss sex/gender issues as little as possible?

Discussing politics is not productive. The political opinions held by most people don't affect actual politics. Discussing politics would be a waste of time even if it wasn't mindkilling. I make a point of never reading local political news and not knowing anything about my country's politics, as a matter of epistemical hygiene.

Gender relations and understanding, on the other hand, are important in everyone's lives. I can't ignore gender like I do politics, and I wouldn't want to. On the contrary, I want to become rational and virtuous about gender.

So I very much want to have discussions about gender, unless the consensus is that our rationality is too weak and we can't discuss this subject without causing net harm (or net harm to women, etc).
