Living in a liberal pest-hole, I got to see quite a few Liberals become very quiet in September, 2001, and a number of them do a 180° course correction in their attitudes. Often, it did not last all that long.
But if a city is lost, it will be one of those, "I never voted for Richard Nixon" things.
If Manhattan were to go, preaching about "We deserved it" or the "Brotherhood of Man" would take more courage or stupidity than many Liberals could conjure up, as it would be a death-defying act.
The "Monkey-at-the-Wateringhole" displays of the Finsbury Mosque types do not reach the levels of fury some people have about 9-11.
We wait.
My wife says those on the left tend to hate themselves so they tend to accept negatives.
Thomas Jefferson said something of the sort that 'the two types of people are those that trust their fellow citizens and those that do not.'
I don't think Jefferson is that far off but I think my wife is more accurate but I am not sure.
The libs holed up just long enough to avoid getting punched in the mouth for saying the things they wanted to.
