"I disagree, I think it’s a reflection of lack of critical thinking skills when it comes to political topics. People are so polarized now they have lost the ability to discuss nuance, see the other side, or really compromise at all."

I think this is generally true, but I also think HN is one of the more open minded places on most of the topics. I think the main problem I have seen in political debates on here are when someone automatically assumes a scientific finding should be policy. In reality, we as a society need to figure out how to apply that finding in a way that balances multiple concerns and fits with society's other rules and values.
