Hard to make much of a comparison between a dying out and antiquated groups of jerks in the south, and a similar scenes that has come from nearly every terror sponsoring middle eastern country, who hates America, and Isreal in the middle east daily. That includes Iran right on top. Better call a spade a spade when you see one, and racism and religous intolerance, is more than prevalant, from these countries. Their leaders are at the top of that mentality and run those countries, where the USA government is not the heads of the KKK and and that is not our american culture or midset. Certainly, these people are not "every" middle easterner, and they have been welcomed into this country. Actions speak much louder than words, when seeing the actions of those in control of Iran and those who support that, on the bigoted side of their culture. You have entire cultures who would distroy ours in a heartbeat. Wiping Isreal off he face of the map, is not an idle threat, its is a declared mission.
Thankfully in this country the KKK is a dwindling minoriety(sooner the better), tolerated only by our Constitution that gives them free speech, as the cost. But in the middle east their brand of bigotry controls entire countries, what they are taught and how they are treated. No doubt, whoever makes it in a President in Iran, severe penalties will follow, to those who demonstrated against him. They execute without reservation, womans rights are non-existant in places, and the true meaning of oppression commands their culture. Even sitting completly out of their affairs, Iran has blamed the USA for thier riots today. Thats the level they hate America, we have nothing to do with their elections, or what internally happens inside Iran.
