Difference though in that many Mexicans that came here legally even some illegally feel more allegiance to America then the do Mexico... they make up one of the largest groups of foreign nationals fighting in our armed forces right now... I don't think the Muslims that are doing this over in Europe are of that same ilk.
Many muslims enter Europe legally since many European countries have far more lenient immigration laws. Many muslims in Europe are hard working and loyal to their new country. Lastly, most European countries barely have forces that could realistically be called armies.
The difference (and it's a BIG ONE) is the Mexicans ARE CHRISTIANS! They tend to be more religious than most Americans.. They are good people and make good neighbors here in San Antonio.
