There's obvious parody (which the original campaign kind of skirts at the edge of), and there's outright impersonation.

A reasonable person should be able to tell the roast from the real deal - the original website was at the very edge of it, the Twitter account is right off the cliff.

You're right, free speech is such a hassle. People who have the temerity to make fun of foreign oil corporations should definitely be imprisoned.

Free speech doesn't cover fraud, defamation, and libel - all of which are already illegal.

So basically what you're saying is, impersonating people is wrong, but it's ok when we don't like the person/group being impersonated.

Do you have principles, or is your morality purely based on convenience?

The second, of course.

Just like how its legal to shoot terrorists, but not Americans. All morality is based on drawing tribal lines, and BP isn't in my tribe.

It's legal to shoot American terrorists if they're in the act.
