I don't think I'm far off in saying that if you were to take every comment made on Reddit ever and break them down into categories it'd look like this:

60% pun / meme

15% complaints about Reddit / Subreddit

10% sarcasm / misogyny / white knighting / racism / lying / grammar nazism / general bullshit that exists wherever you go

5% neutral boring observation / failed joke

5% opinions that are written quickly without thought and are often presented angrily or with some sort of contempt (though still have some merit)

5% well thought out, well presented, and non threatening opinion

I don't know about you, but of all those I generally skim over the puns, memes, complaints about Reddit, and the failed jokes, which leaves us with the 10% bullshit and 10% thought provoking comments. Between those two, which would stand out to you more, the one that threw you into a furious anger or the one that made you go, "huh" for a second before moving on to a gif of a dwarf handing a battered prostitute an upvote?

So even though these comments may crop up at times and greatly stand out to you, I really do not think they are representative of all of Reddit (even if they get upvoted it's rarely without controversy). Hell, I don't think you can find anything that is representative of all of Reddit, except that we all use Reddit.
