Most stuff on here doesn't have to be content warned. The warning is for assuming the gender of the viewer not for the target audience for the meme. For example, a meme saying "you are a girl" needs a CW while a comic about a girl saying how much she loves being a girl doesn't. The posts needing those warnings are fairly rare.
I don't think I've seen anything that would need the other CW posted here to begin with.
I'm also not a very active moderator. I'm only checking here about once a day and I'm usually more concerned with comments since that has historically been where the issues have been. This community doesn't have a lot of activity and has largely been supplanted by others on this server.
