Well, my opinion only, but I believe that if they let gays into the armed forces, then there will be lots of trouble.
And I still hold to the belief that it's only a rights issue.....it's happened here in Australia, and still happening. In the 1960's the White Australia Policy was still the order of the day, the aboriginal peoples actually had their own schools (which their kids never showed up much at), and the whites had their schools. The abo's squealed discrimination etc etc, the law was finally passed and the abo's could attend the same schools as whites.
The outcome ???? The Aboriginals won the RIGHT to go to the same schools, but did they attend those schools ???? NOPE !!!! Nothing changed other than the aboriginals now had the RIGHT !!!!!
And so I believe is the issue now facing you all in the USA.
