In 1950, the first Gay activists said:

We need a happy word to delude people into believing that homosexuals are not evil, wicked perverts. Therefore, let’s call ourselves “Gays.”

In 1950, the common meaning of the word “Gay” was “joyful.” Well, those 1950 Gay activists and later Gay activists were very successful in deluding many people.

Now, we needed to find an honest word to reeducate the deluded in the true nature of homosexuals. Since Gays are perverts we came up with the word “Gay-pervert.”
