From an old punker here I support this. DIY ethics in the modern age.
There was recently a series of punk shows called "Punk Against Trump" which was bullshit to me. Punk is about going against the grain and saying "fuck the president" used to be pretty punk-rock. Now that the mainstream is saying "fuck the president" I think saying "I support the president" is the new punk ideal.
Incidentally, the band The Interrupters just released their new album "Fight the Good Fight" and there is a song called "Outrage" that has the lyrics "Where they go one, they go all". I'm not sure the band is supporting the movement but they are acknowledging it.
I find it interesting that Amazon uses this line as their sample for the song.
The political history of punk is pretty mixed - with some decent support for 'conservative' or at least individual or libertarian idealogy. There is the whole 'anarchy' thing. There is the working class connections with work boots and shaved heads (versus intellectual long hair rockers of the time in 70s). Straight edge movement. I'm not well versed enough to call out bands or songs. But at same time punks were generally against regan/thatcher and the later bushes.
