You absolutely do not have the right to post a sign like “No Hispanics” at your restaurant, under current US law (Civil Rights Act of 1964). You do not have to wait for an actual hispanic person to show up and be refused service to be liable - the presence of the sign alone is already in violation and can get you fined or imprisoned. You cannot claim “This sign is just for decoration as an expression of my 1st Amendment rights, we would never actually enforce it.” In this way, the Civil Rights Act already does abridge your right to write any sign you want, ironically in direct contradiction to the “Congress shall make no law” language of the 1st Amendment.
I stated the amendment pertaining to my comment.
