See, this is the problem with multi-culturalism. If you accept everyone into your country and say that their culture is as good and valued as your own, you have to accept their culture.
So if the Muslim culture in Pakistan, India, and Bangladesh, for example, is to hate and wish to destroy Sikhs, Hindus, Buddhists, and Christians, you have no basis for saying they should change their ways in your country to conform to your norms.
Muslims: OUT!!!
Sikhs: IN!!!
Hispanics: PLEASE HOLD!!! Meanwhile, line up in order of least tats...step forward, ladies ;)
