What was your full original comment? I'm the founder and currently one of the owners of the History_Memes stream, and I'd like to know so I can see if it's within the stream's rules. One of my objectives in creating the History_Memes stream was to encourage rational and productive historical discussion and debate, and I want to make sure it lives up to that mission.
The History_Memes stream is not intended to promote any political ideology, nor is it primarily intended as a place for political discussion. I don't believe that the moderator was acting with a political agenda, as I have encountered people of various ideologies who believe the atomic bombings of Hiroshima and Nagasaki were unjustified or justified. Nevertheless, I believe that it's up to debate, and I've seen valid arguments made in favor of both positions. As long as the debate is conducted in a civil manner and doesn't devolve into a toxic keyboard war, I see no problem.
