For the final time, a boycott is certainly your prerogative - but I'm sure they will more than make up for your business with the 19 million illegal immigrants in the country, not to mention the growing LEGAL Hispanic population that would rather bank at Wells Fargo than your bank with a separate line and identification process (maybe fingerprinting and strip searches) of everyone who is not lilly white.
Y0... master of the cut & paste... Shooooooooosh! We heard you the first 5 times. And you know what, you obviously don't live in a border town. Try visiting one on the US side and see what the illegals have done to it. Get a clue.
Let's assume that 60-80% of Americans think this immoral. Let's assume that 20% of Americans are disgusted in this and willing to act. Such a loss could be potential. Given that most Americans have been here longer and have larger savings (due to higher education rates/inheritance), it would have a much bigger effect. Boycotts are one of the most effective methods we have for these kind of situations.
Morals first, laws second.
Now a website specifically for this would be good. Any webmaster here? My thought are you have a website on businesses that support illegal immigration, and you get voluntarys to hand out fliers everyones and a while; just to get the message that these place don't deserve our business.
Thoughts?
