If you want to say that it is always irrational to believe in someting without sufficient evidence, then it must be true for all circumstances. I have demonstrated it isn't true for all circumstances, therefore the claim is self-refuting and itself irrational.
Rationality, as it pertains to belief, is by definition is required to be based in fact (i.e. evidentiary).
Words mean things. Very specific things, in fact - not what we wish them to be.
