Well, hipsters often like each other and they are a decently large faction. Also, I think hipsters might be disliked because they are overly intentional about being deviant ("I was in to them before they were cool" as a way to try to one-up someone, etc.)
As per a recent comment this thread is meant to voice contrarian opinions, that is anything this community tends not to agree with. Thus I ask you to post your contrarian views and upvote anything you do not agree with based on personal beliefs. Spam and trolling still needs to be downvoted.
