It’s their need for attention. Rock and Tab were actors and actors definitely crave attention. All those gays who prance around in feathers and outrageous garb in their special gay parades crave the attention. The men who choose to speak like little 12 year old girls with lisps? There’s that attention, again. Women who choose to bulk up, shave their heads and walk spraddle legged as if they have a set of baseballs in their pants? Attention. Attention. Attention.
What does that have to do with their homosexuality? That's the kind of attention homosexual actors definitely didn't desire back in those days.
Movie studios worked ot to make sure stories about their homosexual stars didn't get out. They had their homo male stars date Hollyweird starlets to throw off the scandal-mongers. Insiders knew the truth, but the general public had no idea.
