Colibri is probably not going to see this thread until the weekend, but speaking as a non-GQ mod, I think the big problem is this part of the post:
This is not a comment about hypothetical protesters, it’s an off-topic political comment about real-world environmental protesters. Colibri says ralph214c has a history of that, so he took that into account in deciding to hand out a warning.
I’ve also fixed the thread title so it’s clear warning was given in GQ, not GD.
