Oh, not torn about how I feel about it. This guy is the perfect example of how basic rights can be abused and used as a shield. Whether I like it or not, they have the right to express their beliefs...as fucked up as they might seem to me. Frankly, though, I don't see this as them exercising free speech. They've said their piece, and they continue to do so. This crap, though, this is harassment.
I firmly believe in free speech. But beyond it being a right, it's also a responsibility. I'm not a violent person, and I know violence doesn't really solve anything, but I'd take the karmic backlash for the ability to just fuck this old bastard up. Really, though, I should just laugh and feel sorry for him. Not only because he actually believes his bullshit, but because his firmest, fondest, and most ardent wishes are not going to come true, and he'll leave this life with no legacy but a footnote in history as a useless, delusional twat.
I agree with most of the comments to the linked article: this is all about attention, they WANT you to protest back. Do yourself and the rest of the world a favor, don't respond to their hate with more hate. Laugh at them, deride them.
