Ever stop to think they were booing the question? The fact that he exposes himself (no pun intended)opens him up for reactions such as this. His service is respected; his lifestyle is not.
We have had to grant special status to homosexuals and told to shut up. Just as this soldier exercises his free speech and freedom of association, so too did the audience.
With gays, it is “Hi, I’m GAY” first and foremost. That they are soldiers, or teachers (or whatever) appears to be secondary to their gay agenda. This is an indicator of the narcissism that permeates their “me first” thinking. It is they who can’t seem to “get over it (being gay).” In essence, they are proclaiming their “special status” and expectations to be coddled like babies.
