The sentence that you quoted argues that Chu’s decision was unwise. But,
(1) An unwise decision is not necessarily made on impulse. Some people think long and hard before acting, but their thinking is so corrupted that, the more they think, the further from wisdom they get. That makes them unwise, but it is the opposite of impulsive.
(2) I don’t think that Callahan is saying merely that Chu made a decision on impulse. That, alone, would not amount to *veneration* of impulse. Callahan seems to be saying that Chu is in fact *proud* that she decided on impulse — that she’s not merely enacting impulsivity, but recommending it.
I didn’t see anything like that in the article.
