But without down-votes you end up with silly facebook and 9gag content. If you stoically see downvotes it should not alter your mood. You are the master of your mood, not the random people that dislike your comment, or weather or politics. Imagine a large feed straight with news, and all get only upvotes - general population will upvote cats instead of any actual news. There is no way how to combat low quality content if you have option only to upvote. It does not work in /r/all, but downvotes are very crucial part of every smaller subreddit.
