Although i grew up in a home with religion, somewhere along the way I concluded that all bibles were fiction, all characters passed off as deities fictitious or exaggerated, and recognized that God may or may not exist.
Being non religious doesn't make me spiritually or morally void. I would assert, perhaps arrogantly but primarily by default, that my pinkie is on an astronomically higher moral and spiritual plateau than Rush Limbaugh, Pat Robertson, and George W Bush combined.
My belief system is primarily rooted in logic and reason (From the word reasonable). It's about listening to a wide variety of opinions, gathering factual information, observing life around me, analyzing and synthesizing this information, and reaching the best possible solution or course of action based on the best information available.
Of course I will be wrong at times. Yet part of being reasonable is being willing to change courses when new evidence surfaces. And of course reasonable people can reach contrary conclusions. That's much different from faith, a word that implies that you believe something without having a factual foundation for that belief.
For example, if you believe the earth was created 10,000 years ago but irrefutable fossil evidence shows that belief to be false, a reasonable person changes his mind. Any person who wouldn't change his mind in that situation may be a "person of faith" but they then become an unreasonable person. And as history has shown us, unreasonable people are responsible for almost all atrocities inflicted on the earth.
Nevertheless, I don't have a problem with people having "faith" so long as it doesn't cross the line into unreasonable behavior that adversely affects others. (Having unreasonable thoughts is fine, acting on them is another issue.)
If you don't want to go to an agnostic meeting group, don't go. If you don't want to wear clothes woven of two kinds of materials, don't. If you don't want an abortion, don't have one. If you don't want to do yoga, don't do youga. If you believe gay marriage is wrong, don't have one. If you believe sexually explicit videos are immoral, don't watch them.
Hostility towards religion would require me to force people to do things that I or government have no right to force them to do. Hostility does not mean that I disagree with you.
So I'll respect the right of the religious to live as they see fit so long as you respect the right of the non religious to live as we see fit. (Absent obvious wrongs passed off as either.) That's not hostility, that's the dream and vision of America. And if some religious people are hostile to that dream and vision, the next plane to Saudi Arabia leaves the airport later today.
