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

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

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

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

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

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

A belief in a god is not the problem.

Any straight men had a gay experience in the past? What was it and how did you feel?

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

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

Do "flat-earthers" attempt to sail around the world to prove their theory? Would this support their belief in a flat Earth?

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

THE BIBLE IS THE PROBLEM!

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.

J.K. Rowling said that 65% of people in Britain are transgender. Where did she come up with that statistic?

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