Me personally, from my position as a Christian, is I would rather sit down over a glass of sweet tea or a beer, your choice and just talk. We can talk about fishing, hunting, why the earth isn't flat or anything that pops up and I will be happy to listen to your stories of why you believe what you believe and if it's reciprocal I will tell you mine, void of any scripture crammed down your throat and at the end of the period of conversation and beverage we'll walk away with a new appreciation for each other and will have hopefully imbued new perspectives to life in each other.

Heck, I've even had the opportunity to do this with that heathen NCHillbilly I'd do again at the drop of the hat too, if the opportunity presented itself.
Life is way simpler than the misinterpreted blather found in the internet and I find that most folks are good people and much more interesting in person than the persona they accidentally or intentionally force upon others in cyberspace.
