Many things that our intelligence agencies do disturbs me as well, and in fact the policy on the NSA telecom cooperation case as well as other areas where I consider the government to be acting unconstitutionally are my biggest gripe with the Obama administration.
Back to marijuana betonsports: I still disagree. That type of betting is strictly prohibited, and while I think that law should be removed, it is a perfectly valid law to enforce, despite its being driven by a desire for tax revenue and a large dose of hypocrisy. The fact that the provider of the service is not in the US means that they generally will not be gone after as long as they remain outside the US (assuming they are not breaking their own country's laws) unless their own country agrees for some reason that they should be extradited. However once they set foot on US soil the US govt is well within its rights to arrest them. They did break a US law interacting with people under US jurisdiction. The appropriate marijuana comparison in my opinion, would be when a US citizen mail ordered marijuana from someone who is allowed to export it under their local laws. Ignoring any illegal actions taken by other people to get the drugs into the US, should the marijuana dealer be immune to arrest when they enter the US?
As far as the "must leave china" comments, I agree, and now I see why you made that comment. I sometimes tend to disconnect specific comments I want to respond to from the larger discussion, so please don't take any comments I made as implicit agreement with the people you're already arguing with. ;) And I'd tend to say that just about everywhere is much more towards the middle of the freedom spectrum than most people believe. Its just so much easier to think in black and white than all those greys that make up the real world.
