It's a riff and disparagement of the saying "Black Lives Matter", which in and of itself rules out any funniness, imo. That it's about threatening violence against pedestrians just makes it worse.
Could be taken as a riff on “all lives matter”, the racists’ retort to Black Lives Matter. But then you’d need to have tiki torches and klansmen being run over.
The sub exists to make fun of those people sharing their message with silly stickers.
The redditor actively doing the same (obviously not just making fun of the car owner).
So obviously this sticker and mod are fucking awful, but it's worth keeping in mind that, if you're at a protest or even just crossing the street, it doesn't matter who's right when it comes to a car vs the human body if push comes to shove. I've seen protesters (rightfully) call out a car for trying to push through them, but they also started mobbing the car, which in turn panicked the driver who then recklessly sped off. Thankfully no one on foot seemed seriously injured, but it made me wonder what they thought was going to happen by surrounding the driver like that. Protest away, but keep your safety (and others) in mind, too.
So the woman who in frustration said the "DDD, you're next" words to insurance company denying her claim is charged with terrorism, but this is fine? even though a lot more non-CEOs have been killed this way on multiple occasions including last week, compared to that one CEO killed in an act that wasn't even terrorism.
Funny but I saw the original post and I’m pretty sure the point was to mock or chastise the person who had this bumper sticker, not celebrate it. So it doesn’t seem inconsistent to allow it while also removing that comment.
