No reason justifies disbelief.

[BrianSoddingBoru4]

Any reason which causes disbelief would be intellectual dishonesty.

Reason does not cause disbelief. Such claims are ridiculous.

And you don't justify your disbelief, rudeness and hate with claims of being reasonable.

1. I disbelieve in Santa Claus, unicorns, leprechauns and gremlins for the reason that there is no good evidence for their existence.  Intellectual dishonesty would be to believe in these in spite of the lack of evidence.

2.  Reasoned disbelief is the foundation of human progress.  Claims to the contrary are ridiculous.

3.  Yes I do.  So take THAT, Mister Poopy Pants.
