They are making all American Latinos look bad. They are causing racial issues where there were none.
Chavez actually was a third generation American from Yuma AZ who marched against 'wetbacks' (his word) and could have never developed the UFW with the dilutive effect of unlimited, illegal immigration. He really understood the need to integrate Mexican Americans fully into the society with language and education.
What baffles me, is how the Service Workers Union which is a major demonstration organizer/backer can expect to organize illegals. Will illegals pay union dues but not pay income taxes?
