who does my own latino race get so offended that I don't know how to speak spanish?

I'm latino as well, I live here in Los Angeles, Ca.........But unfortanetly my mother never taught me spanish (although she is bilingual in both languages). So I grew up never learning the language in school or at home. Here's my thing that gets on my nevers sooooooo F'in bad! A lot of people will come up to me asking questions in spanish and I will polietly respond and say "I'm sorry I don't know how to speak spanish"...........are you ready for it?<--------and they actually have the never to ask "WHY?"............so to me i'm thinking but I don't say it outloud (well except for a couple of times with really rude people) "ummm, this is the United States of American and english is the dominat language.......so if your going to be living here then you should learn to speak english and not expect everyone to speak tortia language" I never bothered to learn the language...........well simply becaue it was of no use to me! I'm a grown man now and why should I waste my time learning spanish for a few dumb latinos who don't want to learn the countrys language they live in? This is a major reason why I have grown and learn to hate my own kind. Through out the years of growing up, I was always tormented and messed by my own kind because of this and other reasons they would pick on me. Yea, some people call me white-wash, but hey, white, blacks and asians never gave me as much problems as my own kind so I can honestly say I don't regreat at all turning in a few latino people to the immigration services that pissed me off............LOL! (it was in high school and college when I did it,.......I just watch them get taken away with a big smile on my face). So tell me......WHAT THE HELL IS THE BIG DEAL ABOUT A LATINO NOT KNOWING HOW TO SPEAK SPANISH IN AMERICA!>?????
