To ask for, or even assume there exists, rational reasoning behind anything done by leftists is to be forever disappointed.
Rational reasoning does not exist in the irrational mind and irrationality is required for modern leftism.
The closest we can come to an honest explanation is simply because they, the leftists, convinced themselves it is a good idea.
Another requirement for a modern leftist mind is the inability to relate cause to effect over time.
So, the blatant and obvious fact that the importation of savages is an ongoing disaster wont even register on the minds of the left’s shot callers.
Modern Leftism is Destructionism.

Rational or not they have reasons for doing this that they think will benefit them. Money, power, control, the advancement of communism are common reasons motivating leftists. Its hard to see where any of these are advanced with the import of muslims/africans. There is one reason that may explain their behavior, an irrational hatred of the West, Capitalism, and conservatism. As Alfred said in the Batman movie, “some men just want to watch the world burn”. They hate the current system so much they want to destroy it at any cost. Whether they survive the change doesnt matter to them. It explains why every concept of western civilization from economics to sex, gender, logic, science, morality, tradition, history, etc is rejected and under constant attack.
