I agree that Islam has an agenda. So far we have very few Muslim-dominated areas in the US.
But I can't fault a business for catering to the Muslims in their area.
The Koreans do mix fairly well, but they still eat a certain way and the restaurants in their area serve their kind of food.
And the Koreans don’t have an agenda that’s threating to Western culture and values whereas Islam does. One Western-style pizza parlor that changes it’s menu to accommodate muslims is not the end of the world by any means. Similarly, a single brick set on the ground in Germany isn’t a big deal either unless you put a lot of them together to build the Berlin Wall. Korean businesses are only there to make money and to serve their communities, which is great, and they don’t have a worldwide agenda of domination.
Or, just take the bowl of rice and dump it in the soup.
No one else does that.
