Religious Obsession

In the past month, I have been looking,  listening and researching certain parts of peoples religious views,
not every religious person, but mainly the famous religious people, like Margaret Court, Anne Wildacombe, Stephen Green
Rick Santorum and so forth. They all have 1 thing in common, 1 thing which they seem to obsess and bring up constantly,
and it's homosexuals, you never hear them bring up anything else from the bible, like, the sun goes round the earth. You don't hear that one quoted very often do you?
You don't see groups of wild eyed closet astronomers attacking astronomers who state that the earth goes round the sun. But when someone stands up
in defense for there bigoted and ignorant views, they act like the victim, as if we are attacking them, when they are the one with
over obsessed and highly irrational view, its like our lives effect there's, like they wake up every morning and we're there.
They need educating, and not from the bible, but from reality. What is there obsession? I really don't understand, someone please
tell me why they are so obsessed with homosexuals? This is one of the reasons why, I do not like relgious peoples views!
Its one of many reasons why I'm an atheist.
