Good post, we should all be willing to accept that we may be wrong. I'm a Christian but understand it's possible God doesn't exist. Of course, I think it far more likely that God does exist, mainly because of the perfectly complex nature of our world. Even something as simple as my hand amazes me, and I can't logically attribute its creation to long term evolution due to random chance. A lot of things outspoken "Christians" say I usually disagree with, but I feel like it's the outspoken ones that usually have the most radical and illogical viewpoints.
I might as well combat Planr's brother's arguments with my own.
-"Evolution is not supported by the fossil record."
This seems baseless, I've studied evolution and the fossil record does often indicate evolutionary trends. At the same time, the fossil record does not give us a guarantee that the earth is truly millions of years old.
-"The intelligent design movement is based entirely on scientific evidence."
Of course, because intelligent design is a scientific theory. You can't use non scientific evidence to support a scientific theory.
-"The LGBT movement is not for marriage equality because they do not accept child enthusiasts marrying young teenage/pre-teenage kids. They have left those people out so far."
I'm not sure why you picked child enthusiasts out of the lot. The same thing can be said for polygamy, incest, or bestiality.
-"The Crusades are not comparable to Islamic Terrorism because the Crusades are incompatible with Christian doctrine and teaching, while Islamic Terrorism is consistent with Islamic teaching and the example of the prophet Muhammad."
Yup
-"The existence of evil is actually proof of God’s existence. Because evil exists, that means there is a transcendant standard upon which we can judge that something is good or evil. Otherwise, evil is relative and is just an opinion."
No, if God didn't exist then evil could still exist, it would just be based on the current societal concept of morality. This could of course shift drastically over time, rendering things that were once unspeakably evil into acts of goodness.
What most atheists don't get is that Christians don't think that Christianity is a religion. It's not a set of rules we have to follow, it's grace that is from our Creator that we choose to accept.
On the money, except it definitely is a religion. A religion is defined as a "set of beliefs".
