Rational

It is both unfair and dangerous to use the terms "irrational" to refer to views we find wrong, inaccurate, and/or dangerous (unless of course they are ALSO irrational). What I means is: If we expand the meaning of "irrational" in the way you seem to have chosen then the word will still have its other meaning (irrational as crazy, inherently contradictory rather than just untrue, and with no sensible means-end thinking involved). And the result of that is likely to be an expansion of mere name-calling.
