Funny thing is, it really doesn't have to be that way. We understand what we say to one another by use of reason. That is the common denominator between the groups. We understand the world by use of reason. The ability to read is a function of reason.
But at some point, there is a suspension of reason because a theist is not content to simply believe. They wish to thrust their belief into the world of reason while demanding that reason be suspended.
If a theist comes out honestly and says, "I see what you are saying but I believe God is responsible. I can't prove it. It's just what I believe. Maybe one day the proof will come out. At least I believe it will. Then science will see."
The atheist can stew over it but can't do anything about it. In fact, the theist takes the high ground because if an atheist attempts to dress a person down for merely their belief, the atheist appears the villain. And rightfully so.
But when the theist transcends mere belief into something they think is on equal footing with testable, falsifiable, reasonable or even derivative of the aforementioned, that is where the trouble starts. They invite scrutiny to their assertion.
Can atheists be a little nicer? Sure. Depends on the venue. When we're talking about theists asserting their beliefs into government and civics, no. It requires a vigorous debate.
And many of the talking points you see bandied about often come from vigorous debates. They sometimes look out of place in a forum because they are not used properly or in full context.
