To give a bit of historical background to the Ongoing Ringer Debate here's Monkseal's take on the casting announcement of Ashley (I've been rereading through series 16 for a bit of light entertainment)
"Ashley Roberts : I feel a bit like Blanche Dubois running around the apartment putting paper lanterns on all the exposed lights saying this, but remember when there was a bit of MYSTERY about Strictly? A bit of MAGIC?! Some FANTASY! An age when, if they got trained dancers on as contestants to bulk up the quality of the dancing in the early weeks a bit, they at least allowed us to pretend, and believe in the supposed basic premise of the show of celebrities being out of their comfort zone. The ringers, they’d line up saying “oh I may have been fully trained, but I got hideous back injuries and it ruined my ability to perform” or “I just sat on a chair in Chicago!” or “I may have been a ballerina in the Iranian National Ballet, but that was 70 years ago”, or “I’m so nervous quiver quake and ever so unprepared woobie lip wobble” or “I’m Danny Mac, you’ve never heard of me, who knows what I did, ooh look my shirt’s fallen off!” and it gave us a little plausible deniability as we watched them smash Deborah Meaden or Daniel O’Donnell into a fine powder. With Ashley Roberts we have our very first contestant ever where my first thought was that…well, she’s just a dancer. She was a dancer, in a dance troupe, that danced, and I know her entirely for dancing (and being a really terrible judge of THE DANCING ELEMENTS of skating on DANCING On Ice). She’s a celebrity dancer, especially as Nicole never let anybody else in The Pussycat Dolls Erotic Revue & Korean Barbecue Buffet Show sing ever. And we already had a prime time Saturday night reality show where the point was that trained dancers were learning other styles and competing for votes, you didn’t watch it guys, I may have been on the other side of that debate, but we had that referendum already, let’s not disrespect the WILL OF THE PEOPLE by ignoring the result with this sort of nonsense. (Please note : all objections will be withdrawn if she either becomes a hilarious cackling take-no-shits villain, OR a delusional pretentious trainwreck like Nicole “ORDINARY PEOPLE JUST DON’T UNDERSTAND WHAT IT MEANS TO BE ARTISTIC!” Scherzinger was on Dancing With The Stars. But her brand is basically “aww gee shucks lil ol me from downhome bumbleton Arizonee” so I doubt it.)"
