I don't know. I wish I did. But it seems there will always be people like this in the world (the one on the left). They won't like what you do, for their own reasons; those reasons won't make sense to you and your reasons won't make sense to them; you could agree to disagree and to leave each other in peace, or try to sit down at a table and arrive at some sort of détente... but no, they'd rather not do that. Is it of some comfort that other people see it the way you do? Maybe a little. After all the hoo-ha in the press about the US boycotting the summit, it was nice to see that even countries like France walked out of this speech.
