Go ask a cowboy, motorcop, or a construction worker if by the mere fact that he wears boots means that he is gay, it’s likely he will want to lay you out flat with a quick one-two punch. As for me…
Yeah, I am gay, and I wear boots as my exclusive choice of footwear. Who cares? I have to say that most gay men I have met would never wear boots in a million years. Conversely for me, I wouldn’t wear their flip-flops or dress shoes.
The choice of wearing boots has nothing to do with whether a man is gay or not. He was gay long before he wore anything on his feet. And if someone thinks that he is straight and could “become” gay by wearing boots, then I have a bridge I can sell him. You name the bridge.
Life is short: get real.
