IMO YouTube ought to be regulated the same way as broadcast media used to, with things like the equal-time rule, but that's not the rule as it currently stands.
There's got to be a good way to get Google to stop censoring one side of the political spectrum, but if we have to resort to legislation or regulation, we're doing it wrong.
If we can't, then I guess Google really is too powerful.
Edit: Google is evil. But Google is also free. If we can't counter the first without eliminating the second, then we have failed as a society.
You could satisfy it, by discussing, say, gun control, and presenting two contrasting viewpoints: One that all guns should be banned, and one that all guns, except for ones used by police and security guards should be banned. A distinction without much of a difference (That is well within the scope of very limited political orthodoxy) is a contrasting viewpoint.
Really, what we need is the web back. That is, the web as I remember it in the 90s, before Google came along, when groups of people who shared similar interests would link to each other and form webrings. [1]
To every political question, there are more answers then "A" or "B".
Are you going to give equal time to someone who wants to ban all guns, someone who wants to ban all guns in cities, someone who wants to ban all guns for people with criminal records, but not mental illnesses, someone who wants to ban all guns for people with mental illnesses, but not criminal records, someone who wants to ban guns for non-citizens, and someone who wants everyone to have a state-provided machine-gun? What about the other permutation of these viewpoints? Or are you just going to dump these questions into a 'left' and 'right' bucket, and say you're done, when the buckets weigh the same?
Relatedly: it's also much easier to come up with factually incorrect bullshit then it is to refute it. Any insights on how you want to deal with that problem?
