Or, to put it another way...
I once had a close friend (who is no longer my friend and won't even return my phone calls) whose wife claimed she had concocted a drink she called Pep-Up which WOULD GROW BACK my friend's receding hairline with healthy hair.
I told both of them I didn't believe it was possible. They got very defensive, angry and sullen and the friendship ended badly.
To remain friends with them I would have had to do one or all of three things:
1.Keep my opinions about Pep-Up to myself.
2.Not contradict the hair restoration claims.
3.Pretend to be "open" to the idea it really worked.
None of the above was I willing to do.
Why?
I have a right to reality. Period. End of sentence.
Nobody can make claims which infringe upon my access to reality or create a friendship hostage situation.
(P.S. Scooter (that was his nickname) never grew hair back in all the 30 years since that argument.)
The Atheist can find no reality in the claims of believers. It is not GOD which is being denied but only the CLAIMS of reality.
The idea of praying to Thor would just as silly and objectionable to an atheist. Why? Thor is imaginary.
An Atheist can only deal with the reality of claims. Going beyond that is infringement.
I personally don't see how being an Atheist is possible. What I deny are the claims for reality which I have encountered so far in religion.
I think it is possible that God (or gods) is a completely unknowable reality--but--only as a possibility.
That is as far as I can go. Saying there IS NO God isn't a statement of fact; only an opinion based on lack of evidence.
