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

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

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

THE BIBLE IS THE PROBLEM!

Does a person with schizophrenia hear voices?

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

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

Do you think President-Elect Donald Trump won the presidency fair and square, or do you think the GOP resorted to blatant unlawful practices to tilt the election?

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

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

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

How do I develop the patience to read books?

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

A belief in a god is not the problem.

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

Why would calling me an incel help anything? How does that solve anything? Why can’t you actually be helpful and offer productive honest advice?

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?
