He cant possibly have as valid a view as a woman on what its like to be a woman
Obvs, exactly as I can't possibly, for example, have as valid a view as a woman of colour on what its like to be a woman of colour. This is a really important point; nowhere are you saying "men can't have an opinion" - that it's necessary to point this out is a reason why we still need feminism. Even though "Do we still need feminism?" wasn't even the OP.
Both pieces in those links I dropped are written by men.
