Me too. Some really bad people hide behind "religion" to get involved with other people, and then do horrible things. *SOME* not all, of course, or the whole concept of religion and morality would be a joke.
But as for our topic here, I have been in that situation myself when I was not active in church for a long time. I would shy away from anyone discussing religion or related topics, because I felt ashamed of how I was living at the time -- I really should have known better. (and, on a similar topic, people who fall away from their faith generally fall really really far away... but that's another discussion).
And of course, now that I'm back in the correct mode of life, any discussion of church, faith, God, scriptures, etc., makes my family and most of my friends just cringe. So I usually don't get into any deep discussions -- that's one of the reasons I love this Forum :) I can talk about it here!!
