Most Atheists Just Talk to Themselves

I've found it to be the case that most atheists just talk to themselves, as most Christians just talk to themselves. I can't back those statements up with any scientific polls, I know. But it seems true for all I know. If true, I have one answer as to why this is true. When people identify with a group, any group, they want to influence that group and want the recognition of that group. So atheists write about issues of concern to atheists and Christians write about issues of concern to Christians. There will always be fewer people reaching out to others because of this. Your thoughts please. *People have recently told me they cannot comment here, and I don't know what to do about it*
