FWIW, it's possible both for hostility to be universal and for it to be harder on some subgroup if either (a) that subgroup tends to be socialized in such a way that they're less equipped to deal with/push back on hostility or (b) that subgroup tends to be more agreeable or threatened by hostility by natural temperament. But overall... it doesn't matter much to me. Reducing universal hostility seems like a positive goal no matter what. Even reducing localized hostility that I'm not subject to means that the potential pool of contributors who might be able to help me or others with problems on SO is larger.
