Because, it is not the flag of the United States of America...if you want to fly the flag of Mexico, go to Mexico! If you think that you are smart enough to tell us how to run this country you must be smart enough to run Mexico! God knows, no one else is running it.
I don't understand why the ILLEGAL IMMIGRANTS want to come here and be discriminated against, why not go to Mexico and use your intelligence, your skills, your knowledge, and your ability to organize and build a country in Mexico. They need help and it is YOUR country!
Go home and build a better Mexico then you can show US how it is done!
