Girls Into Girls!! Why is it Trending

Nicki Minaj, Lady Gaga, Amber Rose? and these are the ppl our children are looking up to? I'm not knocking these ppl, i just wanna know what is so damn cool about girls liking girls? It seems to be the new #tt (trending topic) I amost feel uncool that i'm not bisexual. almost like how it was when i was coming up if you were a "virgin" it was uncool.
