The implicit assumption of this article is that ideas approved by current members of community are good and ones expressed by the "shameless" outsider are bad. This would, for example, automatically invalidate Pride movement without considering merits of it's goals. It would be more fair to say that regardless of merit of ideas, stating them directly and forcefully despite community pushback can be a valid strategy to attract new members or shift Overton window.
