What's the difference between guillotine memes and that whole "helicopter ride" meme the alt right did a while back? Yeah, the targets are different, but the joke is still literally "lol, we're gonna kill people". Like completely ignoring the fact that it's inflammatory and alienating for some, it's just not funny. I also wouldn't be surprised if some dumbass kid took it too far and constructed an actual working one, and the victim in that case isn't going to be "the bourgeoise".
