Nick,
I take the liberty of elaborating on your point 6).

Western societies are witnessing an exponential growth in the promotional and marketing aspects of product creation and distribution. This hyperbole is extremely evident in the movie industry and the stock market.
Another growth industry is the confrontational one of civil legal actions.
I agree with you that no person, institution, company or government has the right to make insupportable derogatory remarks about another. But, I also strongly believe that the members of a society must have the right to question those things, which others in the society so freely hype.
I'm sure you agree that no one should be denied the right to present fair and honest criticism.
