That's pretty cynical, not everyone has an agenda, I think there are to many labels thrown around, were Christians, don't you think we should act like Christians, without our resorting to labels, that's what the world does to make people who don't share their beliefs, become insignificant.
If you call yourself a Christian you are my brother, I am supposed to love you even if I disagree with you.
But by placing labels on people, we deem them inferior, let's try some Love in the spirit of meekness.
Paul said it like this.
1Cor. 4:21
What will ye? shall I come unto you with a rod, or in love, and in the spirit of meekness?
Considering all of the discussions I've seen on sin, I felt it was a fairly good question, it's very straight forward.
I though it would be a good way for people to voice their Beliefs without all of the discussion and controversy over their particular Doctrines.
Be Blessed
