@layman,
Everyone knows that there's a problem with people who are Muslim committing terrorism. I know that a lot of Muslims want reform. I know that the Muslims in this video aren't that unique. But they are unique for thinking that Trump and the policies he promotes will successfully change the way Islam is practiced in Muslim communities. How would a ban on countries "proven to have a history of committing terrorism against America" help in reforming Islam? Sure, some Muslims who want to hurt America would be kept out, but does that mean we should kick the rest, who are the vast majority, to the curb to die. Have you honestly considered how this kind of ban would affect Muslim communities in the US, who will get the message that they aren't welcome and that the only reason they are allowed to stay is because they arrived before the crackdown. Do you think they're going to be happy that people of their religion have been banned, and profusely thank the United States? Banning people from Muslim-majority countries is not a solution to a complex issue. It's the opposite of a solution.
You might think liberals are spinning their wheels, ignoring an issue, but that's actually because they're not ignoring the issue. They just don't know how to deal with it. Trump has zero political experience, but since he's offered an "easy" solution to a big problem, which he has little understanding of, people think he has everything worked out. He doesn't.
