Kenneth Williams - did he help the gay cause?

For me, Kenneth Williams was an inspirational and brave person who channelled a personal genius into comedy. He is first and foremost regarded as a comedian who played on the image of gay people. However, in my opinion, he also had an amazing understanding of the society he lived in, and, in his various characters, satirised social structure.

However, he was a very unhappy person who eventually, probably committed suicide.

Was he the voice of gay people, and their struggle against a society in which they were very repressed?

Did he help the gay cause?

Or was it more that he compromised his own person, and sold out to the community that only accepted gay people as the target of ridicule?
