Why does it matter so much to atheists that God doesn't exist?

THE BIBLE IS THE PROBLEM!

I do not personally care if you believe in a god or not.

The people of the modern world have evolved past all of that nonsense.

My problem is that people who try to shove their rules down everyone's throats - including by physical force - DO EXIST .

Notice that I said their rules, not any gods rules.

These are man made rules - made thousands of years ago for the use of the humans who lived thousands of years ago.
