Boycotts

Stop Supporting La Raza!
Please call the businesses below and tell them to stop supporting La Raza. We should not be forced to support pro-amnesty groups through our purchases of goods and services. Please send us any contact information updates from the businesses below to: minnsir@yahoo.com

It is important that we cut off the funds to the open-border, anti-American, raced-based group La Raza which is able to influence our government at all levels due to their huge cash flow. Businesses should not supporting one race over another one. We are ONE country and we need to be united as one. We should be looked upon as individuals and should not get funding based on the color of our skin.

Furthermore, La Raza uses this money to lobby regularly on behalf of the political positions taken by the Mexican government against the US; i.e. against US border fencing and interior immigration law enforcement and uses the money to threaten so sue anyone who doesn't agree with their positions.

Here are some articles and information on La Raza:
