Also are we talking about global opinion? A lot of people outside of the western world aren't as big fans of LGBT for example, so if we want to make things more objective those videos should have even more downvotes and hateful messages. And if we're being consistent with what google currently does, these videos should be banned sometimes for hurting others (ex. religious) feelings. People are ok with downvotes and banning, but only if it panders to their current subjective moral fashions.
