Athiests. Should we be using simpler terms when talking to believers?

Perhaps, but I don't like talking down to people. If one writes in a certain manner, perhaps it will "lift up" those who don't understand, make them curious and make them reach and yearn for something they can't quite comprehend. Ah, who am I fooling. Quite.

I get your point, but I promise you it is not a question of intelligence. Believing in gods requires "faith" and faith requires you to surrender your rationality. Having a rational discussion requires both participants to be operating in the same reality. Once a person surrenders her rationality it becomes impossible to reason with her. Christians live in a world where angels, demons, and talking snakes are real so you've lost the debate before it started! I fully understand this now. It is like trying to talk to a patient who has been hypnotized. My training tells me that you can't feed the delusion, but reason and logic are also ineffective.

There is a saying: A person doesn't care how much you know until they know how much you care. Religion makes it connection through emotion not reason and that may be the only thing that can loosen its grip.

Perhaps you are correct that a person should explain every complex term they use.

But its slows down the conversation or debate.

Did you feel you could never ask the person to define those terms? Most atheists that I know are more than will to help educate a person.

I don't even know what a false dichotomy is, but I am well versed in all of the logical fallacies associated with Christianity

When you atheists have been at your ministry for 2000 years then maybe you can flip the world around. Otherwise... get your axes, torches, and lions ready.

I think so. It isn't fair to use unfamiliar jargon with people, because then they don't have a chance to understand your point. And it makes us look pompous

Honestly, why should I dumb down my communication for the willfully ignorant? People will become enlightened when they choose, not because I bring myself down to their level.

I think you totally should, because it makes you look like the pompous pricks you are and will continue to ensure that you're only talking to yourselves.

atheism took on a generation of hipsters and a lot of them like to use big words to feel smart and superior

I'm an atheist because humans weren't created and prayers aren't answered. Pretty simple, really. God does nothing.
