It seems to me the greatest complaint heard about religious people is their lack of open-minded thinking. And I am sure we've all met the old woman muttering about how all the kids sexing up today are going to hell, or that youth group leader who was just a taaaaad overenthusiastic.
But these are not the "rule" of religious people. These are individuals who believe a faith, but are unwilling to let others believe their own beliefs.
Agnostics and atheists quite often pride themselves on not holding any such narrow-minded beliefs themselves. However, I'd like to comment that I have seen people of this belief share the same problem. "People of that one faith are always so judgmental" is, in fact, a judgment itself. It's the same thing as that God-fearing old lady saying "Those hedonistic atheists don't care about anyone but themselves!"
The fact is, people of all walks of life ought to--and often do--respect one another's beliefs. Jews, Muslims, Wiccans, Atheists, Agnostics, Buddhists: any of them can have an open mind, just as any of them can have a closed mind.
Religion, or lack of religion, has nothing to do with how open your mind is. And as I have faced that stereotype myself, I wish people would stop judging others based on that.
