It all sounds lovely :"Of course those at The Register enjoy free speech, which should be the right of anyone..." - oh no, off the rails and into the ditch - "... But it seems to me that those at The Register are taking unfair advantage of their captive audience ..."
Things are clearly different in the Land of the Free, because here in the UK I choose to read The Register when and as often as I wish, and don't feel any coercion when I do so. Also, just how is expressing an opinion or having a bias (real or perceived) in any way taking advantage? If The Register was tasked with the responsibility of educating gullible and formative young minds, I would agree there was a duty of care. But I'm a grizzled adult, with all my prejudices, bigotries and idiosyncrasies fully-formed and running smoothly. Plus, being an adult, I find I am capable of hearing and reading opinions which differ from my own without feeling the need to curtail someone else's right to express them.
It's a common error to assume that the right of free speech contains a right to be listened to. In fact it does not. If I don't like The Register or its tone, I would quickly look elsewhere. I suggest you apply the same principle. It's sort of like a free market, which is another thing the US doesn't fully understand. Don't get me wrong. I've lived in the US, and I like many Americans individually. But your government really sucks, and you claim, as a so-called democracy, that you voted for it. So you have to take some of the blame for that.
