Seems like they could well succeed in destroying scouting. If the Scouts do allow gay scoutmasters, a lot of parents will probably find something else for their boys to do, membership will decline, perhaps to very low levels.
If Scouts continue refusing to accept gay scoutmasters, it seems like the forces of political correctness (these days including churches, temples, local governments and school boards) will continue to ostracize them, perhaps until they are successfully demonized.
Scouts may well be screwed no matter what course they take.
The only hope that I see is that the kind of folks who want their kids in scouting are those who believe in absolute values, in other words, not "liberals."
It is blatantly obvious to me, not just on the part of the militant gays, but all liberals as well. They want to destroy our basic precepts of freedom and self-reliance in order to create another communist/socialist Big Brother USA.
When you stop and compare where we are now compared to even a few decades ago, you can see that they are succeeding.
The title to G Gordon Liddy's latest book says it all: "When I was a Kid, This was a Free Country."
