Somebody Explain This One to Me

Somebody explain this one to me:

Amnesty International: Important despite the wasteful diversion of some of its energies and resources in campaigns against the arms trade and for economic, social and cultural rights

Is it:

• A droll bit of leg-pulling?
• An unfortune omission of essential commas?
• The whole truth?

From Maverecon. He also says

The Church of England: Not perfect - too few gay female bishops, for instance - but pretty good

Which seems straightforward enough.
