If another 9/11 occurs and I see someone cheering, they will pay. I don't care one bit what the world would think either.
Well, not to be tin foilish, but... if that happens, and Americans take arms and begin shooting Muslims indiscriminately, then this country will be launched into civil war- because half the country would want to keep their guns, and the liberals and the rest of the world will want to take them away. We'd be fighting amongst ourselves with the world and the liberals squarely against us.
I believe in justice. But I believe their purpose is clear- destroy the United States. And by using our freedoms against us, they may very well do this if open season begins on Muslims here in the US.
