had a relative who "worked in Hollywood"
(she was a private secretary to a major director before going to work at MTM - mary tyler moore's production company. she talked to about how louis mayer - of MGM - had no sense of humor and did an impression of him that others in the know said was "spot on'")
essentially - EVERYBODY in the industry knew rock hudson was gay
the "secret" had to be kept from "middle america" - the population that continued to believe liberace just was a good, wholesome lad who loved his mom....and his "brother", george
's relative had loaned a car to rock hudson a numerous ocassions
he was a very pleasant - easy to like - fellow who put on no airs
unfortunately - Rock Hudson had to live in a time when not only did Hollywood have a strong anti-jewish sentiment
(read Growing Up With Chico by Maxine Marx on details of that)
but a world where homosexuality would get you arrested
that so many performers have announced in recent times that they are gay or bi is a VERY recent thing
moving pictures might have discovered sound approximately 100 years ago
but having a genuine moral backbone is still in development
