It's not easy to give a single, clear answer.
Quite a few posters have referred to "old-style drag" as in Dame Edna Everidge and Lily Savage. Danny la Rue went into drag performance (1950s/60s) after being told he was good at making people laugh and should concentrate on that www.theguardian.com/stage/2009/jun/01/danny-la-rue-obituary#:~:text=Yet%20what%20La%20Rue%20achieved,saucy%20jokes%20and%20sentimental%20songs. I remember several comic drag acts in TV sketch shows in the 1970s - Les Dawson and Roy Barraclough as Cissie and Ada, Stanley Baxter did sketches in drag in his comedy show, drag duo Dr Evadne Hinge (George Logan) and Dame Hilda Bracket (Patrick Fyffe). Then there was Kenny Everett, whose drag name in the show was Cupid Stunt, "all in the best possible taste".
I was a teenager in 1970 and didn't know quite what to make of these drag acts and sketches. I never liked Hinge & Bracket and I didn't find Cissie and Ada very funny. I liked Barry Humphries as Dame Edna Everidge and found Kenny Everett's drag sketch incredibly provocative (bearded man as "woman") but it made me laugh. Danny La Rue was all ruffles and old-fashioned elegance (from a previous century), so I wasn't interested in him.
I was after something clever and very funny. Hit-and-miss. Never liked pantomime dames, so when in my 60s I saw some Drag Race episodes (because friends liked them) I was curious. It's artifice to the nth degree, but there's also artistry at times. No-one else I know watches it apart from this small group of much younger friends. It's like a secret vice, mostly harmless, but can be addictive. The formula isn't that different from any reality tv show. There's wit and creativity and stories of overcoming difficulties in life, not merely smut and innuendo. The costumes and makeup are sometimes extraordinary.
Perhaps watching that drag show is the antithesis of everything else in my life. It's an escape. I had/have no idea why men would wish to perform as women, and being unable to imagine it properly, got drawn into to the stories they tell.
I was interested in the discussion here because the show under discussion is Strictly. I don't like Strictly and part of that not liking it is (ironically) all the artifice. How the women must dress in high heels and revealing gowns. The illusion of a man lifting a woman when the woman has to do just as much work as the man does, to make it look elegant. How the woman must be smaller and lighter than the man. I'm nearly 6ft tall and have never learned to dance. I feel clumsy. I can't wear high heels. I don't wear makeup.
So if a drag queen is to appear on Strictly, it's not so important in my eyes. But I can appreciate the dislike of drag queens per se having considered the discussion here. If I were a big Strictly fan, no doubt I'd feel differently.
Also, I agree with the posters who say that the drag queen persona is not the one that should compete - it should be the man behind the act.
