The one where masculine men in Hollywood have to appear in public in drag, typically wearing a dress

I like the link you give that includes three scottish men wearing kilts. And you think this is some big conspiracy. Scottish. Men. In. Kilts. 🙄

Actors like to show off and get attention. Wearing a man-skirt will get attention.

Actors often do comedies. Putting a man in drag is an easy way to get some cheap laughs. Sometimes very cheap.

This goes way back; like 2010-2011

Fourteen years is "way back"? Are you six?

Straight macho men dressing up in drag for shits and giggles goes back to at least the 70s and probably even more, and has nothing to do with the rainbow mafia. It was particularly popular as an end of year celebration for footballers.

There is a long and honorable tradition of cross-dressing in film and plays going back to the ancient Greeks (who did not allow women to act on stage). In the twentieth century, long before gay liberation, Sir Alec Guinness played Lady Agatha D'Ascoyne in the 1949 movie "Kind Hearts and Coronets". Possibly the oldest examples in 20th century western cinema are Charlie Chaplain, who played "wife" in the silent movie "A Busy Day" (1914) and Wallace Beery who played the female character of "Sweedie" in the series of the same name.
