This comment doesn't make any sense. How can banning everyone from particular countries - from babies to the elderly and everyone in between - possibly be justified on the basis of security? That is not security, it is paranoia. How many white nationalists have killed people in the US over the past decade alone? Would we think it is reasonable for countries around the world to ban the entry of all US citizens based on that. No, we wouldn't! No double standards! No hypocricy!
