Sexism is already a problem we're actively dealing with in Canadian society. We're going to keep dealing with it, immigrants or not, until it's no longer a problem (hopefully sooner than later). You're acting like we're just letting them be sexist when in your own examples they keep getting fired for their unacceptable behaviour. Eventually, everyone from "sexist immigrants" to "sexist rednecks" are going to learn what is and isn't accepted in Canadian society.

None of this rhetoric actually supports your racist, anti-immigrant attitude. We're neither importing a new problem, nor are we allowing immigrants to break our social contract without facing appropriate consequences.
