I think it is because her philosophy is naive in that it only considers the economic angle, and extremist in that by doing this, it takes market-thinking to it's brutal extreme.

The market, and the self-care that drives it, are wonderful mechanisms, and have brought great wealth. But (stating the obvious) humans need more than being able to buy and sell at will. They need health-care, education, welfare, etc (even if their parents / family happens to be poor). There are other factors than market-fairness that a civilized society should take into account. Not doing so is economism. And almost every one of us probably knows someone who would have been left to rot/die by Rand'ists if they had it their way.

So I would not say it is (just) hate that makes people stop listening when Rand comes up. But rather a kind of (not very laudable) impatience with naivite, that might be familiar to anyone who ever did any teaching, or for example tried to guide a novice elderly person through using a computer.
