We need to be talking about the political implications of what we've built, and figuring out how to fix our mess. This is like the period before the hurricane: everyone should be busy boarding up windows, and you can't do that if you decide you're just not going to talk about the coming storm because it makes you feel bad.
Silence assists certain forms of repression.
"Can we stop with the politics" doesn't take away your right to protest or discuss politics _elsewhere_. It just means someone is tired hearing the same arguments rehashed over and over on HN.
