Speaking as a small provider who gets these kinds of takedown notices, America is actually pretty good when it comes to political speech. Perhaps the best in the world. if you get a takedown for political speech, nearly any small provider would be happy to fight for you, because it's wonderful publicity. (I say small provider, because in order to fight for you, someone with enough authority to do so has got to see the takedown, and decide it is bogus. At large companies, the people reading the takedown often don't have authority to decide to fight or not. the same incentive applies, though, so if someone at a large corporation with authority saw a bogus takedown for political speech, they might make the same decision a small provider would.)
I know I'd be happy to defend original political speech against a bogus takedown notice... not because I'm patriotic or altruistic, but because the publicity would be priceless. this is America, and my customers are nerds; being at the center of some scandal where the feds were trying to shut down some opposing political viewpoint would be incredible, from a self-promotion standpoint.
America becomes a bad place when you want some kind of commercial speech (or when your 'political' speech is commercial... but even then, so long as it's clear you have a valid claim and are not just copying someone else's copywritten work, it's pretty easy to find a provider willing to fight for you in order to garner the positive publicity.)
I might be willing to stand up for political speech, but I'm going to cooperate with taking down customers who want to violate trademarks to sell knock-off goods (knock-off goods are fine, just don't violate trademarks.) I'm also not going to spend a penny defending people who want to share movies or other copywritten data. Right or wrong, that's not a fight I can win here in America.
I keep telling my customers this; if you want to say something politically controversial, do so here. if you want to copy the latest movies, etc... host in eastern Europe or china, and don't involve me.
