My father was a war veteran. During a debate on “Don’t Ask, Don’t Tell” with me years ago, he shared his thoughts on why straight men in the military were uncomfortable with gays serving.
It had nothing to do with sexuality, my dad explained, but instead came from an interpretation of weakness. He personally had no concern about someone hitting on him, but he was convinced a gay man would lose his nerve in battle and cause my father to die along with him.
That was based on the way my father grew up, thinking the only gay men he knew were the extremely effeminate men he saw around town and misinterpreted their character and womanly gait as frail.
