There is a history of inclusive radio in the UK which goes back at least to the 1960s. Anyone who was born here and is over the age of about 50 will know about Kenneth Williams, who appeared in radio comedies with Hugh Paddick. The material is dated and may be regarded as clichéd and demeaning now, but they played two gay men called Julian and Sandy on a show called Round the Horne from 1965 to 1968, and the same characters came up in later shows as well. Bear in mind this was on national radio at a time when gay sex was still illegal in the UK. See https://en.wikipedia.org/wiki/Julian_and_Sandy for more details.
