I'd say the main reason is that there aren't enough people using the forum as a whole, but even on other forums where I am a member, real engagement with debates is poor.
I think important reasons are groupthink and identity politics - people often don't want to really engage with those who they see as on the other side of an issue because they see them as somebody to be defeated, so they look for any way to win (or appear to win in front of whatever crowd they believe is present) the argument.
I'm not sure how many people now really think about what somebody who they are debating has to say, and whether in fact they might have a point, whether there might be something interesting they can learn ; it's simply incompatible with your objectives when your politics are part of your identity and you want to win the approval of those inside your 'in group'.
Given that we see no platforming and cancel culture in our finest universities, among people who traditionally were open to ideas, it's not a surprise that debate is struggling elsewhere.
