The comment about free will wasn't about Jason Collins' choice, it was simply placed into my post to touch on God's hand during births.
And the general idea of believing anything is that you're taught, at a young age, to believe many things...until you're told, usually by the same person or one of similar authority (parent or teacher) that it's incorrect, or that there are differences.
Growing up, young Christians are taught the Bible, just as a Muslim is taught the Quran. If two Muslims had a baby in the United States, and decided that he should be a Christian (which would never happen, but let's apply it here), then he would understand the Bible as taught to him, by whichever minister those parents selected.
What makes things unbelievable (translation-wise) would be the nature of killing in the Bible. I'm almost to the point where I think Christians SHOULD believe (according to the book) that murders are justified, because honestly, almost every person on this Earth has sinned before, after birth...and when you dip deep into the words of the Bible, it's pretty shocking how things turn out for sinners.
I know a lot of Christians (and even a minister) who will say that people misunderstand scripture, and that not everything in the Bible should be taken literally. Why not, though? It's pretty obvious why that's the case, if you've read through it from front to back.
So when a human being is put on this Earth with gay tendencies as a young child, too young to focus solely on image and too young to care about one's sexuality, and he/she grows up to be a great person based on today's standards in society, I'm going to refuse to believe that said person should be stoned to death in the same way I don't believe someone getting drunk on his birthday should suffer a similar death, or an eight year old child that steals a pack of gum from a convenient store should die.
