Multiculturalism is like AIDS, it destroys the host country’s ability to defend its culture from attacks from virulent societies. In a functioning immune system, the macrophage doesn’t negotiate with the infection, it doesn’t take into account the feelings of the bacteria, or whether it has a valid point of view. It doesn’t respect it’s diversity. It attacks and eliminates it because to fail to do so means death.
Islam/sharia is like Kaposi's sarcoma or thrush. An opportunistic infection.
