Those kinds of condescending and trite dismissals are just not interesting. Rand draws more than her fair share of them and I don't think an honest debate can be held over her (good) philosophies because of their prevalence.
Ayn Rand (and in my experience, most Objectivists) didn't want an honest debate "I am not looking for intelligent disagreement any longer.... What I am looking for is intelligent agreement."[1] (I recommend the whole essay.)
Thanks for the essay. It's unfortunate Rand and Objectivism are so uncompromising. I guess that leaves the debating and exploration of ideas to us laymen, and we all know that won't go anywhere productive or intelligent :)
