Do you actually believe that this is only going to be for a few months?  And do you actually believe that it's only going to apply to people from those countries?

As the article points out, Ali's son (a US citizen born in the US) was given serious grief when he and his other returned to the US from outside the country.  He was asked if he was Muslim and detained for hours - funny thing is, they let his mother go thru because she had a picture of her together with Ali.

This lady from Canada was held for six hours and told not to come back without a visa - only thing is, she's a Canadian citizen, born in Canada - she does not need a visa - her "crime" appears to be that she's got brown skin (and her name doesn't suggest that she's Muslim)

But, if in doubt, all you have to do is look and see what is happening to the US tourism industry
