I didn't say that it wasn't offensive at all, nor did I say that there are no circumstances where women might get a a 'better' deal, so not sure why you have responded as if I did.
All I was saying was that we need to be consistent.
Both on the basis of principle, I don't think that casual, generalising sexist comments aimed at men are any more, or less acceptable than casual, generalising sexist comments aimed at women. Nor that casual, generalising racist comments aimed at white people are any more, or less acceptable than casual, generalising racist comments aimed at black or asian people, for example.
But there is a pragmatic element to this too - if we tolerate casual, generalising sexist comments aimed at men, then some men will see this as double standards and feel either (not unreasonably) aggrieved and will think this therefore gives them (our of fairness) the justification to make casual, generalising sexist comments aimed at women (which is not reasonable).
That's my point.
