Are you kidding me UppittyNegress? Are you actually suggesting that Mexican men and women give up their identity and assimilate into the "American identify". Are you really asking them to do something Black men and women continued to reject? As a descendant of those who were robbed of everything uniquely ours and having that replaced with everything uniquely European you now want another group of people to do voluntarily do that very thing? Tell me you are kidding.
No people in there right mind would give up anything that is uniquely theirs in this day and this is why we have urban enclaves of every race and ethnic group that is built around their culture, their religion and their languages. It is only natural that Mexican men and women would do the same, and if we still had everything that was uniquely ours we would do the same as demonstrated by what our continental African family members are doing.
As far as Mexican men and women waving their flag, you actually expect them to do something Black folk don't do in large numbers, We don't wave the America Flag today, did not wave it after 9/11 and yet you want Mexican men and women to wave the America flag?
