I haven't had a chance to read all the comments yet, so apologies if I'm repeating anyone. I just had to comment!
I'm a Christian, a full-on Jesus freak! Totally in love with God, and I don't care who knows it. But I admit that some of the things the institution of the church has done throughout the ages are awful and totally unchristian in fact. I think it's always important to remember that people are people. Unfortunately humans have a habit of perverting things for their own ends at times - all sorts of things. People of all faiths and none had done dreadful things. Atheist states such as Stalinist Russia have caused horrific suffering too.
As a person of faith I do feel a have a duty to be very careful with my behaviour and words and so on, as I think people are more inclined to judge me, which is fair enough.
I'm so sorry to anyone who has had a bad experience of Christians or the church. Please know these things are not of God. He is wonderful & amazing x
