What exactly does that even mean? That we shouldn't pass judgment on Pat Robertson, Rev. Hagee, Joel Osteen and his wife, or Ray "Banana Boy" Comfort, and their ilk who spread hate and lies and steal from the religiously afflicted - unencumbered by either a conscience or reality?
Nor should we judge those who kill abortion doctors in the name of their man-god; or those who decree that gays are not full citizens due equal rights because the bible says they should be killed? That we shouldn't judge those who want this to be called a "Christian Nation"; reject the “separation of church and state” as some kind of liberal ploy; and who would deny the full rights of atheists?
Or shall we ignore those who demand Creationism be foisted on the young instead of the scientific reality of evolutionary theory? Or those who kill apostates in the name of their god? Or those who let their children die from curable disease by withholding medical science, preferring prayer? Or those who would elevate to sainthood an old woman when in reality she was an abusive, sadistic, demented, money grubbing witch (Mother Teresa)?
Why the hell should we not judge people who believe in god? Why are they exempt from being judged as imbeciles, ignorant throwbacks, and sheeple who are deluded by superstition and who follow the precepts of pre-scientific bronze age nomads and 2nd century cultists if it is to the detriment of freedom, reason, equality, and scientific advancement and discovery?
This is not to imply I endorse judging people simply because of their belief (or non-belief) and nothing more. To do so is to make snap judgment, prone to mis-characterization. I have been guilty of this myself.
We must judge people based on their actions and their speech. We do it every day. If their actions trespass on the rights, freedoms and equality of others, on the intent of the founding fathers, on scientific advance, on educational advancement then their actions should be judged and judged harshly - their invoking “God's intent” or citing their book of horrors and fable doesn't insulate them from judgment. To do otherwise would be to relinquish ones right to condemn those who make this world "less' ...never mind if they believe in a God or gods or not.
To hell with those who think they are somehow above criticism / AKA being judged. It is not only our right, it’s our obligation.
