Seriously, there's always the balance between what is *right in principle* but would, practically, generate such a mess, that one should maybe think twice, on one hand, and a practical attitude that denies so much every principle that one stands for, that one has become a total prostitute on the other hand. The right way is in the middle somewhere, no ? It's like a market economy: principles have a high, but finite price. The price you're willing to pay can be relatively high, but when reacting according to a certain principle would cost you much more than what you think it's really worth, you don't go for the deal. Sending in uproar police against a demonstration which is already the fruit of high irrationality and heated minds, is maybe not, pragmatically, the best deal. Letting them have their demonstration is probably the best thing if this can let off some steam from the boiler.
I have to say that I'm quite satisfied with the French attitude vs. the ME (for your information, I'm not french, I only live here, so I'm not exposing some form of silly patriotism), it seems to be trying to find the right balance between principles and pragmatism. That cannot be said about everybody.
