In English, you can say "men do x" or "women do y" without a built in obligation to indicate or to notice to yourself whether you mean all, all that you've noticed, all inevitably, most, or some. I think not having a requirement to be clear about such things leads to a lot of stereotyping and pontificating.

I don't think it's just a matter of language. In Italian it's extremely rare to use a noun without an article as the subject of a sentence -- you'd use the definite article (lit. ‘the men’) if you mean something like ‘typical men’ (as in ‘men have opposable thumbs’ -- male amputees do exist but are irrelevant to the point being made) and a ‘partitive article’ (or an indefinite pronoun such as ‘someone’, rewording the sentence such as ‘there are men who’, etc.) when you mean ‘certain men’ -- and yet people use the former all the time even when they have very little evidence that something applies to an entire reference class except a few irrelevant exceptions.
