Funny, Frank, but that's exactly how I feel about the government! ;-) Just replace "Christianity" and various other words in your post with "the government" and you'll see what I mean right away.

Like this...

You ask me why I left my faith in The Government behind.

The Government is based on an authoritarian mindset. You have a pecking order in which a supreme authority tells you what to do. It is a Big Parent in the Capitol and it bosses you around.
It takes away from the responsibility of an individual to make their own decisions. I realized that if I were ever to grow up and become self-sufficient I could not bow down or pray to a
Big Daddy in Washington (or Ottawa). The Government turned out to be an insufficient source of inspiration. It was contradictory and a jumbled mess of stories that didn't add up to anything important for me.

I also found out that morality has nothing to do with The Government. Therefore, after exploring other possible avenues of belief, that is...other governments, I found them all to be pretty much the same thing, rules and dictums that have no bearing on my day to day life. I would be so happy to be free of all that.

When I left mythology behind I began to appreciate the needs of others. I believe I became a better citizen.
