Christians in the news

I came across this in the online version of ST today:

Christians and Christianity have been put in a rather negative light lately, what with the AWARE saga, homosexuality and the S377A penal code, and now this. What do you make of all these? How can we Christians engage the public meaningfully and constructively without having either sides taking up arms at the slightest provocation, intended or not? (By this I also include the way we maintain this blog, as it is in the public domain.) Do you think it is ever possible to have peaceful, level-headed discussions about one's religious beliefs in society? If we are to influence our culture positively, how can we go about doing it?
