Johnny Rotten is also MAGA.
A lot of punk rockers have gravitated toward conservatism, and it actually makes a lot of sense. In the 70’s punk was a reaction to, and against, both the latent hippy movement and the contemporary disco/yacht rock trends. While initially punks were all about “Anarchy,” I suspect maturity and wisdom have led them to move a little away from that, being happy with, “small government.”
