Btw, it's best to send these concerns to hn@ycombinator.com. I only saw this by accident.
It might be that people genuinely dislike discussion of politics on here even on a thread that is about politics or that Trump's supporters here are more likely to have downvote buttons.
This has been the utopia of the tech nerd mentality for over 30 years since I first started using UseNet. The reality is, this kind "reasoned and fact-based" discussion model (a) doesn't really exist when there are subjective components or unknowably complexities, but worse (b) it is actually used to suppress discussion! The number of times I've observed discussion with people using "logic" to gatekeep is uncountable.
The fact of the matter is: some topics are messy and you can't just throw around "logic" and make it go away. Well, you can sequester yourself, but good luck with that.
