What is the difference between KKK and Al Qaeda?

people are comparing al queda to the kkk.the Al Queda wants to over throw the government that exist and form its own new government.they are people that wants to be government. the old kkk had politicians in the government and was welcomed by the people and the government.they were not trying to over throw the government,they were a a part of it.the non kkk people ,not in the government, invaded the system of government in place,and removed the kkk politicians from the government.so,the two organizations were opposite. the usa was originally a white dominated society and the government was over turned by minorities.what is now called racism or bigotry,was normal in the past.
