Comments like "blood on the hands of $movement", by contrast, are battle fodder. Irrespective of your politics, that's the sort of thing that provokes worse from others and leads to all-out war, which we're trying to avoid on this site. So if you'd please not post like that here, we'd appreciate it.
you're permitting a standard political talking point to be an entire topic of discussion, and then screening out some individual replies because they invoke additional standard political talking points.
you're allowing some standard political talking points and disallowing others. if you're doing that, it would be convenient for your users if you were to specify which standard political talking points are valid topics of discussion, and which other standard political talking points will get your comments banned.
