You'd need a proportional voting system for that to work. Short of a revolution, that's never gonan happen. Sorry Americans, you are pretty much fucked.:(
Blocking the site is a bad idea. A small notification, for example a box in the top right corner of the web page (like the Ghostery plugin), would work very well. Don't be intrusive, or people won't use it.
It should also be more general purpose: net neutrality, human rights, environment, animal rights, etc. Let the user choose what issues they are interested in.
"Sea Shepherd campaigns are guided by the United Nations World Charter for Nature. Sections 21-24 of the Charter provides authority to individuals to act on behalf of and enforce international conservation laws."
Sea Shepherd is not classified as a terrorist organization by any country in the world. They have also never in their history attacked or harmed people, only property.
Care to back up those statements with evidence? I don't know Paul Watson personally, but I don't think he would do the stuff he does for decade after decade and be as successful as he has been if he was in it just for shit n' giggles and money.
I sort of agree with the media whore part though. Apart from their direct action anti poaching operations, SSCS is also trying to raise awareness and affect public opinion (and yes, get donations to fund their campaigns). An NGO with a political agenda needs to be in the media. Media wants juicy stories (sex, violence, scalndals, etc.). That's a difficult equation for the NGO to crack. Paul has stated openly that he is going to give media what it wants in order to advance his agenda. Personally I think SSCS has done quite well in providing interesting stories and getting their message out without being too attention whorish or silly.
The thing is: Chernobyl has so far happened only once. If coal kills one million people every year and nuclear kills one million once in 50 years or so (and I don't think we'll get Chernobyl scale disasters that often), nuclear power is still safer.
