Livre d'Or

people ought to be listened to if what they're saying is (objectively?) useful

Ah, but commonly (in all cases I have witnessed) men saying that feminists don't listen to men are saying things that anyone who has spent a long time in feminist circles has already heard umpty million times, and quite likely something that someone has done research on and shown wrong. For instance most "innate" difference (other than the statistical variation of purely physical things such as height) have been shown to be basically rubbish by Reputable Scientists (some of whom are male) - I don't think that Joe Random pontificating on it being "natural" that women like cooking and men don't is a useful contribution to, well, anything really.

Many men have made important contributions to feminism and feminist thought, they were listened to because they had new things to say that could be shown to be correct.
