I think you greatly overstate any crossover impact the repeal of DA/DT might have in the civilian society. The gay agenda is actually much further along outside the military than within the military. I've never heard of anyone being kicked out of civilian society for telling that they are gay, or being required to remain silent about the fact.
And the military will be still be much more restrictive place for gays, and for heterosexuals for that matter. The great challenge on the civilian side is to find ways to prevent the courts from all sorts of rulings that a good majority of the people oppose. That's already been proven.
Civilian and military life are two entirely different worlds, that is why we have the UCMJ. That is why Congress must insist the military strictly follow the UCMJ. The military is already downsizing, one Art 15 hearing (court)conviction and your career is over. ANYONE having sex in single quarters should be punished, is disrupts good order and discipline. While gays will not be forced out after a Art 15, they will not be allowed to renew their contract.
