Now, please stop, so I don't have to answer a "why was my post about why was my post about being flagged flagged flagged?". Politics is strychnine and meta is crack.
Unfortunately, no we can't. That's clear empirically. We can all come up with speculations about why it is; mine is that politics is tribalism and activates the pre-rational brain.
What's clear from years of experience is that such discussions degenerate rapidly, that the degeneration compounds—i.e. the more it happens, the worse it gets—and that allowing it to go unchecked would kill what's valuable about this site. That's why the HN guidelines' definition of "off-topic" leads with an admonition against pure politics: https://news.ycombinator.com/newsguidelines.html.
There are some political topics that can be substantively discussed here, but that's because they're not pure politics: the drug is cut with something else. An example from yesterday is https://news.ycombinator.com/item?id=12841178.
* While I am interested in broad scocio-political discussions about technology's impact on how we live I have zero interest in US specific political discussion. Not because I think it doesn't affect people outside the US - it does, but because anything I have to say, or anything most people (including US citizens) would say would just be armchair activism or pointless what-if pontification.
* I come to HN mainly for tech discussions and insights into things that influence me and those that I can influence as part of the tech community. US politics is neither of those.
