Mixed children's choir

Podium Speak has a rant about children's choirs, arguing in favor of segregation:

In elementary school choirs, where mixing boys and girls is common practice, there is a sure but steady decrease in the number of male singers. In the high school choirs, they are as scarce as palm trees north of the 45th parallel. This then trickles down through adult community choirs which are constantly looking to bring up the number of the male singers, and the ones that do sing are often considered the weakest of the sections, many of whom took up singing later in their life, and struggle with reading and vocal production.

This certainly jibes with my experience. Mixed children's choirs end up being 75% female. There's a strong argument for keeping boychoirs separate.
