Simon Singh was successfully sued by the British Chiropractic association for pointing out they are quacks. (Edit to add: I just checked and he appealed a point of law successfully and then they withdrew — https://en.wikipedia.org/wiki/British_Chiropractic_Associati... — but as I understand it such a case would be laughed out of a US court.)
Although I'd agree with the general point that whilst America has good theoretically human rights, the EU is better at actual rights (and in particular, rights against corporations).
