It means someone is trying to say the reason you speak out against homosexuality is that you are afraid of it. In other words, they can't refute your position, so they assign one to you that they can knock down.
Have you ever met anyone that was afraid of a homosexual? Where do they come up with this stupidity. Homophobe. Like, I have a phobia. Give me a break.
Well, yes. There was a time when Act-Up could be very violent if you spoke out against homosexuality. So groups stopped speaking out for fear of the harm.
The homophobes are the ones afraid to tell the truth about homosexuality for fear that Act-Up will return.
Shalom.
