Good question. The liberals have been brainwashed into thinking that if we embrace all cultures on earth that we will eventually melt into one great global family. That's what happens when western countries elect former drug-abusing ex-hippies to high political positions.
What we're seeing, from the empirical evidence, is that these different cultures intend to consume and destroy. They're like rabid jackals. You cannot defuse the threat of a rabid jackal by smiling and petting it.
