That isn't the point and it's a huge exaggeration to equate the two. The question is whether or not the President has the unilateral power to suspend travel to the US by foreigners. He clearly does. Presidents have certain powers afforded to them by the Constitution. Starting concentration camps isn't within his power, banning certain travelers for a short period of time IS!!
Obama had a ban on Iraqis, Carter on Iranians. Nobody said a word.
