This site is incapable of having nuanced conversations about this, because opinions that the loudest voices disagree with are downvoted + flagged into oblivion. This is significant when talking about diversity, because it means minority voices are silenced, and without those voices, such a conversation is meaningless.
For example, look at the comments thread whenever "James Damore," "cancel culture," or "affirmative action" comes up. That should be proof alone that HN is never going to have an actual impactful conversation about this... Ever.
I'd prefer if the mods just banned these discussions forever, because it's exhausting, and forever doomed to end up as a "diversity is bad" conversation.
Funny thing is, it looks the other way around from the other perspective.
Maybe what you're seeing is not a bias against race- and sex-based DIE initiatives, but your first taste of balance in discussions about them.
Maybe because you assume that your argument is correct, whenever you see the other side at all, you feel like there's an imbalance, when perhaps it's just that you have a warped view of the landscape of opinions on these matters.
When someone is offered a conversation and results to name-calling and straw-manning, isn't a downvote what you'd expect?
