Have you considered taking my comments less personally? I think Myriad is probably wrong on this matter, and I tend to think you would be correct on it if you added a couple of qualifiers to your knowledge claims. I'm just being honest in stating that none of us is in possession of information that would prove Myriad wrong, and all we can honestly say is that Myriad doesn't seem to have evidence to support his claim and our experience has been otherwise.
Regarding that claim, I thought I had more evidence than it turns out I did. The last time I got involved in a discussion like this was in late 2011, and when I looked at Google Trends at the time, there had been a huge spike in U.S. searches for "Objectivism" and related terms the previous April, peaking during U.S. income tax filing deadline week. That made it appear likely that recent interest in Objectivism had come largely from the anti-tax politics of U.S. conservatism, especially the burgeoning (at that time) "tea party" movement.
However, that spike was not repeated in April 2012. An even larger spike occurred last October, apparently as a result of Paul Ryan being named Mitt Romney's running mate in the Presidential election.
So, while I can make a case that (in the U.S. at least) political events spark interest in Objectivism, I can't quantify how much of the interest in it (especially ongoing long-term interest) ultimately stems from that relative to other sources. If you can point out some comparable spikes occasioned by, say, the publication of a major scholarly book on Objectivist philosophy, that would go a long way toward defeating my claim.
The rest of my experience comes from general-interest discussion forums like this one. This thread is the first I've seen that focuses initially on the philosophy itself. What I usually see is the opposite, beginning in political discussions: "Taxes/unions/zoning laws/carbon agreements/equal opportunity laws/tenant rights laws/handicapped parking spaces suck, and by the way, let me tell you about this great philosophy that explains why."
I still consider the hypothesis, that most interest in Objectivist philosophy is driven by interest in Objectivist politics rather than the reverse, plausible though not proven. Supposedly, I'm entitled to observe the world with my senses and draw conclusions from that, without being expected to be omniscient. So, there you go.
Respectfully,
Myriad
