"But where does their allegiance really lie with the USA or Mexico?"
It's obvious. Which flag did they wave before they were coached?
Of course it lies with Mexico. And their tactics show that the goal is to manipulate Americans to sympathize with them by appearing to be 'patriotic'.
Respecting our laws is 'patriotic'.....Invading our country is not!
I actually heard a CNN reporter ask if calling them 'illegals' was offensive to them?
OMG......the world has turned upside down!
