Why does the Treaty of Guadalupe Hidalgo pique the illegals?

Answer 1

I don't think most no about the treaty, they wouldn't care any way it was so long ago, I find only the Mexican activists put out about it they are the ones that tell the illegals how to act and what went on in history they tell them we stoled the land and that is what they believe, if you have listened to their rallies they always say the same thing, they were here first and it is their continent, they forget they took the land they had from the Indians also.

Answer 2

why? they don't like to know the truth.
