Listen, I've spent much of the last two weeks talking about content warnings on here, but always either in reply to someone asking about them, or simply aloud, without picking out anyone in particular. What I generally don't do is jump into people's replies to tell them that their post should have been behind a CW. It's important to talk openly and often about the norms that make these communities work, but be careful that you don't turn into a cop about it.
