Mexican/American, who's right?

So there is this big deal about some kids wearing an American flag on Cinco de Mayo. In the good ole US of A! Let me start my rant by saying I am both Mexican and American aka White. My mother's father is from Mexico and came here when he was young. He just recently became a citizen and has worked everday since he came to this great country until he retired from the railroad. He speaks english, pays his taxes and has never recieved government assistance. He is very old school mexican. Raised his family with the culture and spoke to his family in spanish. He has a strong accent and looks fresh from the border. He is a good man. He is a proud man. He is a mexican man that is a citizen and has never displayed the Mexican flag. He is proud of his heritage and culture. He is proud to be Mexican, but equally proud and grateful to have lived, worked and raised a family here, on American soil.
My dad and his family are from Ohio. Whitesville, Ohio. Same strong work ethic, my grandparents raising good english speaking kids.
I was raised with a perfect balance. I love Mexican food, have a hard work ethic and speak/understand just ehough spanish. I love both parts of my family and who I am.
I graduated from school in Las Vegas and I remember hearing something about freedom of speech. I remember hearing about God giving us free will. So I ask you, in a time that we have men and women in other countries fighting for their freedom, in a time that these men and women are fighting for our freedom, in a time that of our free will we band together to help those that are in need, why are telling kids that they can not wear an American flag? Why can we not show our patrionism? Cinco de Mayo isnt even a real Mexican holiday and I say even if it was...its a Mexican holiday, we are in American. But here is the beauty of things..because we are in America we have the right, we legally can say and wear what we please. Do we arrest people for displaying their countries flag in their car windows or outside their homes or even from speaking their native tongue? NO..we dont, and I am ok with that. In a time that our kids are forgetting to take their hats off when the National Anthem is being played, or refuse to stand and respect the flag and Pledge of Allegiance...in a time that kids are taking for granted the freedoms they are allowed, that they born with, they want to wear an american flag? why? to tell those "mexicans" that this is our country? Or to somehow diminish this "mexican" "holiday"?
Who was there to stop these "mexican" kids from wearing a mexican flag? No one. Does this mean all Star of Davids should be hidden on Christmas? We live in a country that we can choose for ourselves. In a country that we are free..the land of the free..the land in which people come to for a chance at a better life..why not celebrate it? Why not wear our flag with pride? Why persecute those kids for it? Are we becoming so sensitive that we cant accept an American flag?
You know what I think? I think screw you all. I think the person who made the choice to come to this country needs to accept ALL our rights and the same for those fortunate to be born here (like me, thank God). Nobody gets to pick and choose which ones you like and which ones only apply to you or me! That being said, to all you Americans that feel entitled and think you dont need to show other people respect..grow up. Understand we are all different, we all have different past and heritages and I am proud to be an AMERICAN..but I wont deny that I love my MEXICAN roots..so you ask me..when I wake up in the morning and pull that shirt over my head, will it be an American or Mexican flag..well if we are being honest, the only thing I know for sure is I will be wearing a shirt..because that is a law here in the land of the free..but personally I wont be wearing either flag..the colors for both flags clash with my eyes!
