I'm going to hazard a guess that your mother wouldn't be proud see what you just wrote. So long as nobody gets hurt, anything goes? Lying? Bullying? Cheating? Most of us learned better than this back in kindergarten, I hope you'll reconsider your position. I wish Paul Watson would, too.
As to ramming vessels, the Sea Shepherd folks got their start with that back in 1979 when they intentionally rammed a Portuguese vessel and have taken credit for at least six more rammings since then. The Marley Fowat, another vessel in the Sea Shepherd fleet and captained by Paul Watson, even has a sharpened steel I-beam welded to it's superstructure (Watson calls it "the can opener") that is used to scrape and puncture the hull of whaling vessels. The Fowat also involved in "Operation *******", so named because of the intention to use it to ram another vessel in the stern. Though Watson was one of the founders of Greenpeace, even they have officially withdrawn support for the Sea Shepherd and condemned the group because of their policy of violence and the danger they create at sea. Whether the Sea Shepherd was the rammer or the rammed last year is an open question, however it is undisputed that they were intentionally and willfully in violation of a whole bunch of safety at sea rules and were the proximate cause of the collision. That people haven't been hurt has had more to do with the restraint and generosity of the whalers than it does the Sea Shepherd folks.
If provocation is never an excuse for violence, it sure can be a mitigating factor.
