Sigh. What are you struggling with?
I know you don't like being challenged on your sources, but Sex Matters have a pretty f*cking warped agenda and it's a miracle they have charity status.
Credulous CXR is struggling with the notion of not taking everything you read at face value.
If your source is The Telegraph, and it's being amped by a horrid anti-trans org you probably need to take a breath and take the time to find out the detail.
Firstly, the public record and the internal GMC record are separate. Doctors with new identities cannot circumvent investigations or disciplinary action, so the lynchmob suggestion that errant doctors will declare themselves trans to escape sanction is nonsense.
There may be no disciplinary record on trans doctors public registration because there may be none anyway. Suspensions are removed from the public record after 10 years (or 15 if suspension was 3+ months)
There are 62 doctors in this category (out of 390,000 GMC registered registered in UK), and some of the new registrations are because of threats made to their safety, ie. the huge irony that the very thing the transphobes are complaining about is a result of the actions of transphobes
