So if someone was to say, 'We're going to criminalize Marijuana usage because it'll predominately affect black communities' followed by a law that says 'Marijuana is now illegal' are you insinuating that the policy would not be racist?
Rhetoric in many cases informs policy and vice versa. You can't just say they exist in a vacuum when the reason why the visa ban occured was on racial pretenses.
Muslims aren't a race, the affected countries were about 10% of global Muslim population, and the countries of concern listed in the travel ban were designated in late 2015 under a different administration.
