Well, you're right if it makes you feel better. Clearly males are more dangerous than females and restricting male immigration makes some sense. I could see an argument that immigration should be female only.

That said. Apparently, we're talking about 1% of the population if the article is to be believed. So we're not really talking about all males here, nor even a majority of males for that matter.

Of course that also means we're not talking about anything close to a majority of black americans, but that's a whole other discussion.
