Do you agree with these minute-mens stance on mexican immigrantion and y were they called racists?

I think Americans today have become ignorant to the fact of how and why our forefathers created this country to begin with. People today are saying things like "It's my country...I'm an American they're not!"...but this land isn't our own...this land isn't 'our' country...it's everybody's country...everybody who wants to fight for liberty and justice for all...everyone who wants to have an equal opportunity where their child is promised a coveted future in success...everyone who wants to be free from persecution and just be fulfilled to have and obtain the American Ideal.
