I brought this to their attention recently in response to their gripes against the LatinAmerican community in the following way.
Do you ever acknowledge the help that the Latinos provided for you when you were suffering under Anglo American slavery? How you were received hospitably both in Mexico and in Florida when you fled there and were gladly provided with a chance to start a life as free people? Of course you don't. Instead you encourage your buddies the Anglos to restrict immigration from Mexico and cooperated with them once you were set free, in the harassment of the very people who had offered you a helping hand. How is that for being ingrates?
