I have stated before and firmly beleive that our rights are in the most danger when it seems most reasonable to limit those rights. People on the internet say some despicable things. It seems reasonable to limit the speech of groups like the Aryan Nation or Westboro Baptist Church. They are bad people. But if you limit their rights, you limit every one's rights. And sometimes out of sources we do not like, wonderful things are said.
Lindsey Graham is not some one I would generally be a fan of, and I am not. He tends to be divisive and say some spectacularly bad things. The world would probably be a better place if he would never speak publicly again. But if that happened, I would have missed out on a quote that I think is one of the great comments in modern American politics, one that helped me reform how I view the country and politicians. He said "we became a great nation not because we are a nation of cynics. We became a great nation because we are a nation of believers". I think that is a pretty powerful comment, and very true, and very important. If putting up with some trolls is the cost of every one having the right to say what they think, and we get a few comments like that, I think the cost is well worth it.
