Why Do Gay Guys Act Like They're On their Period aks PMS ?

Their;s this gay guy at my school who is such a b*tch, and acts so mean! He doesn't know that people refer to him as the "heshe f*ggot" becuz he acts like he's on his period. He's not the only gay guy who acts like a b*tch, every gay guy i see acts like a B. Especially on tv...they all act like it. I DON'T GET WHY THEY DO....THEY'RE NOT GIRLS!!! Girls act like bitches sometimes becuz of our harsh mood swings aks pms...and that causes us to be bitches at times. But gays, I don't understand why they act like a B and just sooo girly. WHY CAN'T THEY JUST ACT LIKE A MAN!!!
