I don't see that SteinMart is exhibiting any xenophobia.

A boycott is stupid. Mailbombing a shop because it sells France-related products is stupid. It's un-american and un-conservative. It means you're equating the citizens of a country with its government, which is in essence the opposite of what America is supposed to stand for. Especially when opinion polls show that the french are less opposed (about 70%) to a war than the spaniard of the brits, who are opposed at 80 or 90%, contrary to their governement.
How would you feel if your company suffered from a european boycott, because of something the Clinton administration did? Would you see this as fair, justified, intelligent?
