Then let's see how the military does with only women and gays as “servicepeople”
I don't necessarily agree that serving as a straight man is "unpatriotic"; however, I can't imagine any incentive for a straight man to want to serve under contemporary military definitions. If anything, the desire to "follow in one's father's footsteps" needs to be re-evaluated since Dad's service was decidedly under very different conditions.
Back in the late 60's, I met a young Italian immigrant who, after evaluating the rise of feminism in the US, pointed to ancient Rome and Greece. He explained that once women rose to power, they were soon followed by an influx of homosexuals. Shortly after this, both civilizations collapsed. He then predicted that within my lifetime, if the feminists were not checked, I would witness the collapse of the US. At that time, I laughed. I stopped laughing when Clinton was elected.
