It's a lot better change because people can make up their own minds. It's unrealistic to expect everything to be nice all the time, there ar vile things in the world and people who promote vile ideas, and the most effective response to that is to tag them as such. Oh sure, some whiners will complain about being tagged as nazis or whatever, but too bad, if lots of people think their statements align perfectly with the nazis well then the marketplace of ideas has spoken. Tagging content is a practical idea because advertisers and the like can then choose to avoid content associated with tags that they don't want to associate their brands with.

the tagging is a function of the popular will rather than the output of an algorithm or assignment by committee, and the the tags are associable with discrete media rather than individuals.
