/r/all is not the front page. t_d is not a front page default subreddit. people should not visit /r/all if they dislike seeing the firehose. or get gold and use filters and strengthen your filter bubble walls.
People want /r/all to be a community of stuff they like, without stuff they disagree with. Those people seem to disagree with the idea of a content agnostic platform. How would those people feel if gmail stopped delivering ultra left liberal emails.
If there's a significant amount of content you don't want to see, why are so many people choosing to look at /r/all?
