Why did Israel suddenly acquire a backbone and grow a set of testicles? Why has the irrationality, stupidity, sickness, and insanity briefly slightly ceased? Good question. I voted "Enough is enough."
But this is an irrational, illiberal era -- a true Dark Age philosophically -- and so it won't be long before we're back to full-scale Western self-hatred and self-destructionism. Probably within the week.
The whole world desperately needs a new Enlightenment, a new Age of Reason, and a new and improved classical liberalism in culture and lifestyle. But it'll probably take another 50 or 100 years to even properly begin. :-(
