When will liberals shed their dhimmi masks?

Savage has an interesting entry up where he post's an excerpt from Zippy Catholic's recent entry over at What's Wrong With the World.

I commented on an assertion attributed to Zippy wherein he basically says that as long as liberal perceptions are that their acting submissive to Islam is producing net gains to their ideology, then they'll continue to act dhimmi, but not a moment longer...

In my comment to the post I was really just being facetious. I think that if what we have to rely on from liberals in joining the fight with us against Islam is their perceptions to convince them that liberalism is incurring net losses due to their feigned dhimmitude, which is more or less what Zippy is suggesting, then we may as well write them off right here, right now. With friends like leftists, who needs enemies?

Zippy may be right when he asserts that there's nothing inherent to liberalism which would have them allying themselves with Islam, but has he considered well the implications of his very thoughts on the matter, i.e., that liberals are willing to shed the specious mask of dhimmitude not a moment sooner than their perceptions inform them that they've made all the advances for liberalism that their donning of the dhimmi mask is capable of allowing.

In other words, we're to trust that liberals (who aren't particularly rational, by the way) are going to finally wake up and smell the coffee, realizing (or perceiving) at that moment that Islam is all of a sudden more of a danger to their ideology and all the advances they've made with it, than traditional conservative Americanism is. Comforting thought.

P.S. I see that Auster has posted a lengthy comment to Savage's entry at the bottom of which he provides a couple of links to VFR articles on the subject. I would also recommend this VFR entry from a few days ago where Auster explains at length two likely scenarios which relate to this topic.
