Penguins, Penn and the Falklands

Should one be concerned by Sean Penn's declaration that the UK should cease its nasty colonialist ways and hand over the Falklands to the Argentinians? It is upsetting to be sure that an American should be saying such things but is it any worse than being told by the grandson of a Latvian immigrant that he no longer wants Scotland to be a part of the UK? It is worse since Alex Salmond is one of Her Majesty's subjects and can say what the hell he likes to his fellow subjects whereas Penn has somehow taken upon himself a diplomatic role on the part of Argentina and possibly of the United States. The US posture on the Falklands as expressed by Mrs Clinton is ambiguous to say the least if not downright pro Argentinian. Whereas the BBC is very keen to announce the political orientation of those of a conservative mind (witness the call to identify the Taxpayers Alliance as a conservative supporting organisation) it never does so in the case of those of a socialist bent. Penn is a supporter of Bummer, Chavez and also of Kirchner of Argentina, in other words of a left bent, and the BBC in its website report should have highlighted this. Do not let us forget that Mrs Kirchner in any proper democracy would have been under the spotlight for her and her husband's business dealings which if the stories about such dealings are correct leave a lot to be desired. As Penn doesn't like colonialism no doubt he will fight for the independence of Hawaii, a kingdom subsumed into the USA by the votes of local US citizens only. No doubt he will also agitate for the independence of Puerto Rico, a colony of the USA since 1898 as a result of the Treaty of Paris following the Spanish American War. Being a democrat however Penn would, I feel sure, want the Hawaiians and Puerto Ricans to express their desire for independence by way of a vote in a referendum. Why does he deny a referendum to the Falkland Islanders? Why doesn't the BBC point this out?
