Indeed, we are all grateful that the "conversions by the sword" days are well behind us and never coming back. You make an interesting point regarding charitable people. I had an uncle who was a professional gambler and pawn shop owner. As far as I can tell, he stepped into a church only once in his life and that was his wedding day. He would openly say that he had no need of religion and this earned him the ire of quite a few people in his lifetime.I have met some wonderful people, "give you the shirt off their back for you" kind of people. Then again, I've met some Jews and Muslims who would do the same.
At its best, Christianity inspires by example the best in human nature. At its worst, however, it gives excuses for petty or even vindictive attitudes. ("Those people who want to get green carpeting in the chapel area are evil!" or historically, "If you do not believe in transubstantiation, you are a heretic and I have to kill you!" or "If you say the Holy Spirit proceeds from the Father and the Son, you're a heretic and I have to kill you!") That is tragic and, I believe, unChrist-like.

He didn't puff his chest out and put on a show with it. He just did what he felt was right and then got on with his life.
