I think the end of PC is around the corner and coming fast. It's an insurrection or major terror attack away from being extinquished. In France, it may be ending right now. I just hope it's not too late.
I hope you're right too, but my gut tells me otherwise. The essence of being a liberal is to ignore reality at all cost when it conflicts with what you think should be true. What will it take to turn a Liberal into a Conservative? Probably nothing short of having a catastrophic experience that causes you to rethink your most basic assumptions (ever see "Death Wish"?)
Also, as the Muslim population grows, the cost of taking action gets progressively higher--but its a slow process. Solving the problem will be painful & ugly now, but it will be nearly impossible later. The French think they have time and will opt for more liberal solutions first. This will be a fatal mistake. My take is that France will dither for another 15-20 years before realizing that the frog is indeed in boiling water. By that time the options will either be surrender (by emigration to the USA) or full-scale civil war.
For me, the beginning of the end was when I was 15. I watched the news coverage of the 1972 Olympic Massacre and nearly wretched. I saw reams of analysis on "what the Arabs were really angry about". Little coverage was given to the fact that six athletes had just been shot at point blank range.
Mind you, my natural father (who died shortly after) and I distributed campaign literature for McGovern, so we were still solidly liberal.
It did not last long.
If war between Islam and the West occurs in twenty years, the holocaust of abortion and 'family planning' will manifest itself as the un-Godly, deadly practice it really is. Islamofacists are multiplying like rabbits in Springtime, while (as Pat Buchanan has already stated), the West is aborting and birth-controlling itself into oblivion.
Because of abortion and political correctness the future is certain, they increase, we shrink. They get stronger, we get weaker.
