Language is intimately tied to identity.
So, if you want to really hurt me, talk badly about my language. Ethnic identity is twin skin to linguistic identity—I am my language. Until I take pride in my language, I cannot take pride in myself. Until I can accept as legitimate Chicano Texas Spanish, Tex-Mex and all the other languages I speak, I cannot accept the legitimacy of myself.¹
Take pride in your language.
Not that which goeth into the mouth defileth a man, but that which cometh out of the mouth, this defileth a man.²
