I agree with you on the first point. But I think even the Yes answer doesn’t cause a paradox, since Betteridge’s Law doesn’t state that the answer is “No”, only that it can be (and in this case it isn’t).
And of course in this case it also isn’t a headline, which is integral to the whole concept otherwise it just reduces to “you can answer no to any question.”
If the question had ‘always’ in it, it would be better
It’s a shit law anyway. Fuck this Ian Betteridge clown.
Betteridge? Worseidge more like!
That just reminded me of Worzel Gummidge.
