Liberals have chosen The Donald as their 'Destructor'

Glenn Reynolds: Liberals have chosen The Donald as their 'Destructor':
"...Everyone is aghast at Trump’s latest plan, to suspend all immigration by Muslims.
But it’s no coincidence that Trump’s announcement came less than a day after a limp, toneless speech by President Barack Obama on terrorism, one that left Americans feeling much less safe.
After the September 11, 2001 attacks, then-president George W. Bush made clear that Muslims weren’t our enemy: Radical Islamists were. 
Because Bush took steps against those radical Islamists that made people feel safer, there was no significant anti-Muslim backlash, though all the bien-pensant types thought it certain that those rubes in flyover country would get violent...
Enter Donald Trump.
People who are unhappy with the things Trump is saying need to understand that he’s only getting so much traction because he’s filling a void.
If the responsible people would talk about these issues, and take action, Trump wouldn’t take up so much space.
And there’s a lesson for our ruling class there: 
Calling Trump a fascist is a bit much (fascism, as Tom Wolfe once reported, is forever descending upon the United States, but somehow it always lands on Europe), but movements like fascism and communism get their start because the mechanisms of liberal democracy seem weak and ineffectual and dishonest. 
If you don’t want Trump — or, perhaps, some post-Trump figure who really is a fascist — to dominate things, you need to stop being weak and ineffectual and dishonest.
Right now, after years of Obama hope-and-change, a majority of Americans (56%) think Islam is incompatible with American values.
That’s true even for 43% of Democrats.
In that sort of environment, where people feel unsafe and where the powers-that-be seem to be, well, weak and ineffectual and dishonest, the appeal of someone who doesn’t seem weak and ineffectual grows stronger..."
