lady gaga is simply obsessed with herself but what do you expect from a pop icon? you could probably name a dozen or so acts that came before he that she's ripping off but again that's par for the course.
as far as sexuality being a spectrum, i guess for some people it is. i know i hold different standards for men and women. if a guy does gay shit he's gay in my book but straight women fuck around with other women all the time these days. i've seen a lot of married women get into affairs with lesbians because they like the attention and don't think of it as being the same as cheating with a man, and sometimes the stupid men even agree. it's kind of insulting to real lesbians if you think about it.
i know if i was married and my wife wanted to fuck around with some dyke it would be divorce time.
