This only works if you argue no criticism of anyone public whilst remaining anonymous yourself, was the position of this platform or posters arguing this
The OP claimed the above and that she is not a coward, as she labels MG. And subsequent posts also clearly show doesn't understand how much is at stake career wise for MG, the pressure she will be under from her record company or her responsibility towards the people she employs as her band.
It then transpires that not only does she not use her real name on all social media - which is what Mumsnet is - but she's a SAHM, so has nothing to lose in the workplace.
There's a massive difference between different celebrities. JKR is so rich as to be untouchable financially and has worldwide love over several generations of people, including the current teens. Even she wobbled, but ultimately, if she was silenced forever, she would not starve. Owen Jones uses the bully pulpit and (frankly ridiculous) reputation as a serious commentator and the voice of the left, and has the backing of all manner of unsavories on the SJW side, all of whom can say what they want without consequence in the workplace or on social media.
Every GC woman who is famous and goes public will be in for a torrid ride, social media and career cancellation and much more so than any man doing the same. It is not a fair fight on both sides, we knowTwitter, Youtube, Facebook only cancels one side,. We know that workplaces and schools have been indoctrinated by Stonewall etc, but have not had an equivalent set of training from the GC side, so the Pavlovian reaction to a GC person will be guilty until proven innocent. A GC celebrity female will have a bit of backing, but nowhere near as much as someone from the other side. MG isn't particularly well known outside those of us who remembered her from her work 2 decades ago. Who knows if she can afford to lose this career revival. She's probably already sunk, even with the recantation.
It's not a level playing field between people who are criticised on this board. MPs and journalists with platforms and propagandists at their fingertips are not equal to women with past celebrity, precarious employment and limited financial means.
