More than "insult," the shopowner is IMPACTING an entire community. It's kind of like when the U.S. military murders over a million people in Iraq while U.S. citizens (Jews and gentiles alike) obediently chant "I support the troops," but when one person criticizes anything Jewish (even if that criticism is accurate), that person is labeled a monster. Compare that to Chris Kyle, a cowardly sniper whose first victim was a woman carrying a child, who was even celebrated on the silver screen.
Get your priorities straight.
Why not share here? This "forum" is too tightly censored. In the meantime, Google is your friend. Frankly, I think this jerk took lessons from Bill Gates.
