With respect to religion as with all other things, I believe that what I believe is true, and that in believing it I am correct. Indeed, I think my beliefs are absolutely true. Those who disagree with me, I consider to be wrong about what I disagree with them about.
Do I sound like an self-righteous, arrogant, dogmatic SOB? Actually, I'm just stating something that's trivially and boringly true.
But if it makes you feel better, I should add that disagreeing with me will not necessarily result in your everlasting damnation.
