You are quite correct. There are always exceptions to the rule. Exceptions in both directions of course. For instance, most Tory MP's had a "privliged" education, yet have some important part of their soul missing. non the less.
In the end, we can all be better.
But to some, the slightest effort to try seems beyond them.
btw I saw the post you made only today, never saw a notice.
You are the last person I'd ignore in this cauldron of chaos :)
