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

Those rules that you are trying to reinstate are rules made by men who didn't know anything about the earth, nor anything about all of the other inhabitants of it. How can you not see that?

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

Because these are not any gods rules we are talking about.

If you caught a shoplifter at your yard sale, how would you handle it?

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

I am speaking to the US Bible thumpers here, of course ~ many of whom are flat-earthers who deny evolution and see scientists as evil people who are constantly trying, and succeeding, in disproving their beliefs one by one.

And how do you deny hundreds of years of advancement in all fields of science?

Do you know a good lawyer joke?

And then use and ENJOY these fantastic scientific advancements every single day of your life?

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

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

Can I see some anal hole?

THE BIBLE IS THE PROBLEM!

A belief in a god is not the problem.

IT does not matter, mainly because it does not exist.

Why do some people feel down in summer, specifically in July and August? What could be the reasons behind this feeling of sadness during those months only?

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