Ran into a few playlists of protest songs. A lot of them were 60s or 70s, which is fine but a bit dated. Others were kind of shouty. So I've been off and had a look for some more recent rebel songs - and this is what I've found so far. The Incubus track is the only slightly sweary one.
There are lots more out there and they present a very easy way to bypass complaints that you make too many political posts.
