If you can't get a joke about a major tragedy - you're too dumb for the joke. If you're too dumb for the joke, look it up and you're welcome I just made you smarter
If you have to Google something, it means you're uninformed on the topic. If you're too lazy to Google a major event (example, the Vegas shooter - was big news) then you're not a moderator. Period.
Most of that guys memes are puns on stuff - like "Cook Liberals" for example... Meaning "beat them in an insult battle". Most of it is Tombstones noting the Democrat demise can't come soon enough... Doesn't say how. One had Mr Potato Head pointing out a noose to Swallowell - which is a way of saying "you're going to hang for this" - meaning he will get fired...
Jokes aren't violence. Actual violence is violence
