The BMA

They’re a trade union, not an employer.

And they’re often piss poor on women’s issues

You do mean the GMC. There are rules against bringing the profession into disrepute (they have updated the language, but that's basically what the rules say). However, 'disrepute' is in the eyes of the beholder and the GMC doesn't give a shiny shit about misogyny. If Drs A and C had treated black or gay people online the same way that they have treated women, they would have been hauled off to medical Azkaban years ago.

There's been a few complaints about Harrop to the GMC, dehumanising as his comments were he's said far worse in the past. He's been continued to be allowed to practise as a doctor

I presume dealing with the GMC is what Harrop is talking about here - advising another doctor how to play them.

Imagine going to see a GP who you know calls women 'uterus havers'.
What a nasty dehumanising experience that must be.

Welcome to commenting btw PerpetuallyUnderwhelmed and do feel free to make a complaint to the GMC if you feel it's warranted, the more the better.

I have made 2 complaints so far and they keep saying he's been looked at.
GMC needs to be inundated by complaints then maybe they will do something finally,

I've complained before, didn't seem to do anything, I put him on mute so I didn't keep seeing his hateful comments.
It does need every women who finds him disturbing to complain.

This comment from him seems to treat the GMC with the same contempt that he treats women. The fact that he does this on a public platform shows to me that he clearly doesn’t think the GMC are anything for him to be worried about.
