The problem with your hate speech idea is who is the arbiter of what's considered hate speech and the selective application of the law. We now have a US attorney warning that people could be prosecuted for anti-Muslim speech.
I've seen worse anti-Christian, anti-Bush, anti-Tea Party, anti-conservative in general speech and I have yet to see such a warning in that regard. It's always open season on such groups, but don't you dare offend the religion of perpetual outrage.
