Back in 1972, it wasn't homophobia that caused a ruckus; it was revealing the existence of gay people.
But there's no evidence that Gautier was more homophobic than other heterosexuals in the 1970s; it was only three years after Stonewall, one year after the first gay character on tv, and "things were rotten."
Besides, he had a lot to offer to gay kids in the 1960s and 1970s.
Or as Hal Walters, best friend/confidant/object of rescue of reluctant superhero Stanley Beamish (Steven Strumphill) on Mr. Terrific, which lasted for only 17 episodes in the spring of 1967.
Dick Gautier had over 500 guest shots in sitcoms, dramas, and game shows, voiced dozens of cartoons, composed popular songs, acted on Broadway, drew caricatures and wrote a dozen books, including a murder mystery, No Laughing Matter. He can probably be forgiven for having the same prejudices of many people in his generation.
