In fact it's horrible that some Christian groups by their cynical abuse of good nature, and our faith in the image of 'the good Christian' should sully what is indeed a highly good thing.

I recall recieving a shock one day at work some years ago, and leaving in distress. I recall crying, alone on a street pavement as busy traffic whizzed past...

To my surprise a genuinely well meaning lady stopped and asked in concern if I was alright.
We chatted, I calmed down and regained my composure.
She never said it, but I could tell full well by her entire manner that she was a genuine Christian (noun) - by her christian (adjective) behaviour... With or without the little gold crucifix that she also happened to be wearing.

"Christian is as christian does", with or without a big C, and I believe preferably without cynically veiled techniques of evangelism.
