Not only not tourists... he wouldn't even allow US citizens who are Muslim to return to the country. Which is fantastic, because it is unconstitutional, immoral, AND against international law. Of course, he wants to have the Muslims that stay here wear some sort of identifier so the rest of us "normals" can tell they are Muslim.
Seriously, it took Hitler a couple of decades to ramp his rhetoric up to flat out call for special badges and a ban on Jews coming into the country. Trump got there in mere months!
Like everyone in Germany, Jews were required to carry identity cards, but the government added special identifying marks to theirs: a red "J" stamped on them and new middle names for all those Jews who did not possess recognizably "Jewish" first names—"Israel" for males, "Sara" for females. Such cards allowed the police to identify Jews easily.
At the last group that made a certain religion wear specific identifiers wore are bands too...
If only we had a "final solution" to the Moooslim question...
Seriously though - how do you exclude people of a certain religion without doing what the Nazis did (Your grandmother was a Jew! As if the premise itself wasn't stupid enough)?
"I would like to come to the US of A."

What God or Gods do you pray to? ---*
"What?"
*Seriously, its on the form.*
"Why?"
*If your Moooslim, we don't let you in*
"Oh, in that case, I totally pray to some other God. Not the Mooslim one."
*Okay then, thank you Mohammed. Hope you enjoy your trip.*
