There are plenty on this forum who do not claim that they are always right.

I didn't say 'always' and I was referring only to belief in the supernatural, whether selective or not.

There are plenty on this forum that do not claim that All atheists are always logical and by implication that believers are not.

Implication is often in the eye of the beholder, but are you talking about the logic of specific beliefs or are you making blanket/generalising statements about individuals? I see a clear distinction between the two and I'm not sure which you mean. Non-belief in the supernatural seems perfectly logical and rational to me, for example, but that doesn't mean that, like every human, I'm not capable of illogical and irrational behaviour at times. Likewise there are many believers who may, at least to me, seem to be perfectly rational in other areas of their life. Perhaps the ability to compartmentalise is a relevant factor.
