I mean, yeah I get it's probably a lot of work to moderate all the political related discourse and keep the lanes wide enough for a lot of different voices, but it's the catch that comes with having a "community" in the first place.
If this is the first of a series of "experiments" I wonder which other "conflicts" might "cause harm here" - Identity Discussions? Health care in the US? As cheap as it might sound to pull out a slippery-slope card here, it seems rather apropos.
I get a lot of flack for it here, but if you don't think Politics and Tech are coiled together in significant ways - eg. DMCA and Copyright - then you're just ignorant, childish, and a fool. SV and tech culture is actively using the "Political System" just like every other special interest. Pretending there's some kind of effin' halo over the Hacker News community where such conversations are "below" or "too conflict loaded" then just shut down the forum altogether.
Man discovers fire. Man burns self. Man puts out fire. The end.
