Okay, I agree with that, particularly that we should attack policies, not people. I think there are cases where it is useful to generalize groups that don't have outwardly-stated ideologies (for example, when describing the political leanings of reporters for a given newspaper, or lobbyists' agendas) - with the critical distinction that these generalizations should not be done as a value judgments, but rather as observed trends of behavior for the purposes of rooting out possible effect of biases on information coming from those groups. In the case of reddit and sexism, therefore, I think it would be fair to say that language and behavior that objectifies women tends to be upvoted highly and given more weight by the community than criticism of such behavior, in at least the default subreddits.
