Faith is shaken all the time, even though many don't like to admit it. My own view is that people need to believe in something larger than themselves. It's wired into our DNA. I try not to mess with the faith of others, either in words or deeds. If I find offense at all, it's in the manner that some people try to bring others into their faith and how some belief systems seem intent on ringing the door bell while I'm sleeping (and I don't mean that as a metaphor. I mean actually ringing my door bell while I am actually sleeping).
