I never got the whole #notallreddit thing, it always comes up whenever anyone criticizes Reddit but unlike, say, 4chan, Reddit literally has a content duration program built into. You can just go to Reddit, click things, and see that they constantly upvote bigoted ass shit or shit that didn't happen that paints the evil women as villains or bullshit 'free speech means you can never stop doing anything or the SJWs win' stuff. These are opinions that get large amounts of support from the Reddit userbase, I don't know what other standards exist that can be used to say 'yea this place sucks real bad'.
