just about everyone in Europe is less into gorilla-type masculinity than men in the US.

That's a mighty strong assertion to make about an entire continent that contains countries as different as, say, Sweden and Albania, or Moldova and Switzerland. Also, I'm certain that the sample of Europeans you've seen is unrepresentative in all sorts of relevant ways even of their own countries, let alone the entire continent.

Of course, if by this you mean the specific patterns of behavior characteristic of certain sorts of American men, then the claim is trivially true.
