If apologetics is what you're studying you need to read this former Evangelical Christian Fundamentalist's argument by argument breakdown of the great debate:

Debunking Every Christian Argument

After starting to compile a list of arguments against Christianity I realized that I have said almost all of it in previous posts and in attempting to summarize these posts I would be giving you a watered down version of my stance. If you would like to go through my previous arguments, they are neatly organized here:

All posts by makisupa007 in "God" debate

All posts by makisupa007 in "Creation or Evolution?" debate

So, for now all I have to offer is my publicly expressed opinion on religion and god available in previous posts. If you would like to be more specific about what part of Christianity you want debunked I'd be glad to give it a go.

Hello, my favorite person to give hell. I'd like to ask a favor. I'm doing a study in apologetics, and I'd like to you to give me a few short and sweet accusations against Christianity. Nothin' special, and nothin' to put any amount of time into. Whether in question or statement form, I'd like a few things you find wrong or inconsistent with Christianity. That is, the basis of it, not the flaws of its followers or grammar errors in the Bible-- simply fundamental disagreements.

Thanks a lot.
