How is that different from what the Boy Scouts did?
I think the answer is: that was the unwritten BSA policy before the gay activists and a few big donors bullied the cowardly national leadership into public acknowledgement/acceptance/approval of gay members.
The new outfit is just making the old, unwritten BSA policy official: gay kids can join, just follow a don't ask, don't tell policy.
I discussed this in #24.
(I think a lot of readers here didn't read that part of the article.)
