Neither ISIS nor anything else proves the basic God or atheist definitions.
Bad things in the world only proves the stipulation they wouldn't happen isn't
a credible one to add.
Since the basic God idea (let alone with added names and interventions) is a
possibility, not a proven, you might hope for or not, there's an ethical reason
to not have harm: it would be arbitrary hurting and killing--sadism and murder.
The only points ISIS makes to me aren't about the basic definitions but that
you shouldn't be 'centric or intolerant about things that aren't character de-
terminants, and the basic definitions don't have them. By this view, Stalin's
atheism didn't hurt anyone--his 'centric intolerance about it did. Likewise
the Inquisitors--their 'centric intolerance about God belief hurt people.
I think of how this country has come a long way in the last generation or so
about LGBT people. It would be a lot quieter around here if we just killed all
the bigots about that back then. I think the spread of such information
described above caused the change, yet look at all the racism and conservative
misinformation still going on here (giving Jon Stewart a lot of material) let
alone bigotry over there.
There's a lot of conservatism let alone extremism over there. If police or
even army are needed at times, the bigger change would come about there as
mentioned as happening here.
