A Richard Gere "acolyte"? So anyone remotely well known who expresses an opinion about something to do with international politics is doing so because they are fervent admirers of Richard Gere? Yeah, I'm totally convinced that that is surely the case.

"In world politics they would be up there with Angelina Jolie and Brad Pitt. Mostly light, little heat"

Well Bjork's not a politican so it's rather pointless to point out her stature in terms of world politics. You may as well say "In terms of pop music George W Bush would be up there with David Cameron and Angela Merkel". Nobody's suggesting that two words spoken by Bjork at a concert are going to effect anything massively significant regarding China and Tibet. Are you saying that nobody other than politicians should ever say anything about politics in public? If so, do these politicans have to be elected? If not, when and where exactly are non-politicians allowed to comment on politics? For example, am I permitted to use the words "Free tibet" in a conversation in my local pub?
What is your point?
