I could be wrong, but I read somewhere that Hitler was a Christian and considered he was doing the faith a favour by riding the world of Jews!
You are wrong. Hitler was, like many, baptised into a Christian faith but his 'religion', if you can call it that, consisted of various superstitions, folklore and the occult. No doubt he considered the world would be better off without Jews, gypsies, homosexuals, the disabled and others.
I too haven't seen anything from the BBC or elsewhere about portraying Christians in any light. One is hard pushed to find anything religious on television, not that I want to watch it but a while ago a Christian poster said something about religious programmes that are 'out there' if only I look; all I've found scrolling freeview is TBN which I think is an American channel, on late at night or early hours. I haven't watched it. Don't have SKY, there may be more on that but I wouldn't know.
Returning to the op, I believe that anyone who uses a religion in order to promote something bad (such as abuse of the vulnerable or hate-full politics such as LR outlined), is committing the unforgiveable sin. It's an outrage.
