If you read his other writings on the internet, it appears that he was outspokenly anti-gay. For this, they labeled him with a personality disorder and sent him home pending his discharge. Then he announced on the internet that he was AWOL and demanded that either he be arrested or Obama be arrested. Nobody bit. The army said he wasn't AWOL and the discharge proceeded.
It wasn't not too long ago that gay behavior was not tolerated in the military.
You can expect much more homosexual related problems, that was imposed on them by a Democrat Congress and Obama, for the military as times goes on.
