Would be very interested in hearing what's your definition of racism.

Textbook: discrimination (=unequal treatment) on the basis of race.

And I suppose you don't fall into that definition because you discriminate not based on their race but on their culture?

Of course, who doesn't?

Would you like people who think raping 12-year-olds is fine because their prophet did it, living in your neighborhood, and going from 10% to 90% of the local population?

Some cultures are just better than others. Some are downright evil.
