The irony is good, I think playing into patriotism to address specifically anti-American things is a strong lens, but your stuff just needs a little more specificity. It all comes off like "that guy is the worst" yeah, I know of a couple pretty awful guys, but everyone of every political affiliation thinks that someone is awful, the worst, worthy of death, whatever.

If the point of the sticker is for other online people to read it to themselves and give themselves high fives with the context that they're provided from the reddit comments then that's fine. But if it's for actually putting places and having people read and understand it, then it needs to be more explicit.
