Europe seems to fundamentally "not get" how democracy works. When confronted with something unpleasant, they try to ban it.
The only cure for unpleasant speech is more speech. Anything else ultimately makes it worse.
Or, maybe, Europe has had its fill of radical fascist ring-wing asshats and the problems they cause (read: death, destruction, war, poverty, etc.), and this is one of the tools they use to keep a lid on it.
I predict these views will be censored and modded to -1. For a community that supposedly favors the free and open exchange of ideas, Slashdot isn't very tolerant of opposing views. Voicing my opinion that AGW is a scam will result in my post being censored to -1. If AGW were real, there would be no need to censor dissenting views; the facts would prove the point far better than any moderation. The censorship is necessary because the facts aren't on the side of the AGW evangelists.
Some of us are tolerant of opposing opinions, when they're not outrageously harmful. Hopefully most of us are intolerant of misinformation and FUD, and I hope most of us aren't even tolerant of opposing opinions when they're both clearly wrong and actively harmful. At this point it's fairly apparent that anybody touting anti-global-warming "opposing views" are either pathologically misinformed, or astroturfing.
