Are you kidding me? Somebody says they’re “torn” on whether private companies should allow nazis and racists a megaphone and I’m the one starting a “hellish flame war”?
Yes. That comment was obviously substantive, and it was obviously possible to disagree with it substantively. You needn't look far for examples of how to do that, since the top-voted reply is one.
Since instead you tossed off a Molotov one-liner which empirically resulted in a flamewar, I don't see any question that you started it. This is not a hard moderation call.
When a topic is as provocative and inflammatory as this one, you need to take extra care to post civilly and substantively. This is in the site guidelines. Would you please re-read them and take the spirit of this site more to heart from now on? We'd be grateful.
