re:
"...Refuse to spend your money at Arab-owned businesses
or with businesses that hire them...."
Very feasible and well within all Constitutional rights.
However, you'll be doing away with:
90% of taxi cab companies,
80% gas station/convenience stores
100% of medical services/hospitals
100% of the electronic industry
100% of colleges
99% of auto industry
ahh.... you get the idea?
Oh nonsense. The claims that 6 million Muslims live in this country are wildly over-stated. The number is closer to 2 million, so you would have us believe that in a country of 280 million people the refusal to do business with Muslims would eliminate all of those industries? Mathematically, it just couldn't happen.
