It doesn't matter whether what they say disgusts me or not, I don't have the right to not be offended. People often use Reddit to find news, I believe that Reddit should have a duty to provide that service in an unbiased way without inflicting their own views on the people who use their service. All they should care about it is "is this illegal?"
Yes, I understand that they're a company and not a government agency, it's of course just my opinion that they have such a duty.
