Oh, it's pretty bad. Using masculine gendered pronouns in that way steals individual identity from an entire sex! Unambiguously misandrist. Until it recently became fairly common to use feminine pronouns in the same way, "she" was always a particular person, while "he" may not be. I'm so glad the uncertainty and loss of self is now shared at least in part by both sexes, but we still have a long way to go to equality. </sarcasm>

(Seriously, please use third person plural for this—I still trip over feminine indeterminate pronouns thinking I've missed who in particular we're talking about. Third person plural has a long history of serving this purpose, embrace it.)
