I'm scratching my head trying to figure out how that sentence fits the context of the article. This person organized a protest to keep the policy. So then he warns of a big fall off in membership if the policy isn't changed??
Then it launches off to feature one disgruntled fudgepacker who wants to remake the organization in his image.
I'm willing to bet Comer wasn't booted out of the B.S.A. for being gay. He was booted out because he couldn't keep the "morally straight" part of the scout oath.
