Isn't that written to Michelle by someone else?
It was, but she is the one who has chosen to make a post on her Instagram that highlighted that message over any other (and I'm sure she has received many messages that don't include such controversial points as to suggest that the judges should have shown her any form of bias/positive discrimination based on their sexuality)
I have no issue with Michelle wanting to use her CC dance to highlight LGBTQ community, much like how Will used his to highlight his disability and the huge community of people who have supported him through his life, but to say that the judges should base their votes on their "community allegiance" over the actual ability presented is frankly insulting.
Strictly Come Dancing has always been an inclusive show on TV when it comes to having homosexual representation, nobody needed Michelle to come and "represent" the community that has already been represented on the show for nearly two decades and she should not be encouraging the idea that the judges should be voting in anything other than dancing. Nobody suggests that Motsi should be giving Oti 10s every week because they are sisters and have family loyalty, she is expected to be impartial, as should all of the judges.
Sometimes a bad dance is just a bad dance, regardless of the "message" or "representation" and when it is put up against a dance that is technically good and entertaining then it should be judged impartially and the better dancer should progress. On this evening, that dancer was Saffron.
