Rav Shlomo Miller, the senior Charedi rabbinic figure in Toronto, first became known to many people when he wrote a letter protesting the heresy of interpreting Maaseh Bereishis in naturalistic terms, specifically as done in my book The Challenge Of Creation (but also applicable to any way of reconciling Bereishis with modern science). This letter was posted around Toronto when I visited there a few years ago; you can read it, and a response, at this link.
Recently, Rabbi Miller wrote a letter which condemned an article about women covering their hair, written by Rabbi Michael Broyde of Atlanta.
Now, in contrast to the topic of organ donation, where I admitted that I had not researched the topic thoroughly, the topic of women covering their hair is a topic that I have not researched at all. But what do I see? I see that Rabbi Broyde wrote a lengthy, detailed, article, with copious footnotes. And I see that Rabbi Miller responded with a single paragraph of assertions from authority and insults. And I ask myself: When two people have a disagreement, and one calmly presents a thorough explanation of his position, while the other refuses to do so and simply hurls out angry insults, who is usually correct? When you have good reasons to be confident in the correctness of your position, you don't refrain from sharing them. That's why, without knowing anything at all about this topic, I see Rabbi Miller's condemnation of Rabbi Broyde's article as an endorsement of its arguments.
(And to preempt those who point out that I did not respond to Isaac Betech's disproofs of evolution - first of all, he didn't offer any, and second of all, I spelled out at length my reasons for not debating him.)
