I don't think protest songs are meant to change minds, and don't really have a chance of doing so. They're a rallying cry, a unifying force for those of a similar opinion.

I don't generally enjoy ridicule. Maybe especially when it comes to Trump, because it just plain doesn't take much work.

That said, I don't have a clue what songs Matthew might mean, but all of the rancor is deserved, IMO. If he didn't constantly tweet idiotic statements, he might seem a little bit less like he's asking for it...probably not, though.
