Don't feel too bad. On more than three occasions i've had to use a list of literally nearly every available English dictionary to refute idiots who've claimed men can't be Feminists by showing them that every single definition available states that any gender can be a Feminist. 

 It's both sad, and astoundingly hilarious, that each and every time i've had one or more idiots complaining about a, completely serious, conspiracy of male lexicographers. It's just ridiculous.    Harlequin
