An Alernative Life Style

Arizona prohibits instruction that “portrays homosexuality as a positive alternative life-style” according to Lambda.  I have always wondered how homosexuals are supposedly pursuing an alternative life style.  It seems to me that the basis of life is eating sleeping going to work and pursuing a relationship.  The first two are essential to physical survival, and as far as I know we all of us, straight, gay, bisexual, confused, or repressed, eat and sleep.  Most of us however we approach the erotics of life have to go to work.  The Lord Granthams among us are few and far between, especially in America where inherited privilege and wealth are not so conspicuous as in the world from which the fictive Downton Abby is located.  So there we are off to work every day, all of us.  That leaves pursuing a relationship.  I will admit that once upon a time when homosexual acts were illegal and a genius like Alan Turing whose work decoding the Nazi war machine perhaps more than most saved the Western world accepted castration to escape prison after being discovered in flagrante with another male made pursuing a relationship a journey into fear, danger, and persecution.  Nowadays, however, boys can date, and girls can date, even if in many neighborhoods one must do this at least in part cautiously.  I am talking about the Western world, of course, not downtown Teheran.  So I don't know what Arizona state law means by "alternative life-style," since the style of lives here in the United States seem to me to be pretty much drearily ordinary and uniform.  Maybe I am missing something.
