Well who knows - but heres a little story.
Two gays are walking down the street holding hands. All loved up they are unaware of the not gay guy walking towards them.
As the gays pass the not gay guy - the not gay guy gives them a dirty look - because they are clearly not like him.
Well - the two gay guys decide to ask the not gay guy why he gave them a dirty look. One of the gay guys asks the not gay guy "are you homophobic?"
The not gay guy replies - "YES - I am a HOMOPHOBIC - I dislike the fact that you are not the same as me."
So - the two gays now know that the not gay guy is indeed a homophobic. They have labelled him that.
So the not gay guy says - "Well - you both clearly know I am a homophobic - is there something wrong with me being a homophobic?"
At that one of the gay guys says - "Yes - there is a Gene which says it is in your blood to be a homophobic".
The straight guy says this.........
"Yes - Indeed there is".
Wha'dya'think - cool or what?
