It would be an example of extremism if a voter advocated for the death penalty for Joe Biden for his immigration policy crimes, as Charlie Kirk did in July 2023.
What Joe Biden did with immigration policy, which is basically let them all in, which by the way he promised in his campaign for president in 2020 in nationally televised debates, is indeed criminal to many of us on the right. But we know that presidents get away with murder. We ought to change that, too, but presidents are in fact immune.
