This is the reason I don't attend church, meditate with others, or really discuss my spirituality outside of my home. When it comes to such issues, the nut-to-normal ratio is a bit on the high side for my liking, particularly among those that fashion themselves as 'leaders'. Not saying there aren't a lot of great people in such institutions. But I just don't have the patience to separate the wheat from the chafe.
Why be hurt? The guy can't do anything more than send you an email? Zero character. You're better than that, right? Then don't worry about what he thinks. It isn't worth your mental energy.
