The uk doesn’t have a population registry. Many other countries do and you get a number that is your ID for life, regardless of name changes. That means you can’t hide an identity if you’ve committed a crime with it.
The UK doesn’t have such a thing. It appears to be possible to ‘unlink’ identities.
Now: safeguarding. We have a national DBS system in place because of weaknesses identified after the Soham murders (Huntley had previous convictions but because the system wasn’t national, his past activities were not seen by those employing him.)
If people are allowed to erase a past identity and prevent people from seeing it, or have it stricken from the record under right to forget we create a loophole. In a society with a population registry that loophole would be closed because thevpastvidentity would be visible in the system evennif it’s not googleable. But the UK doesn’t have that, so again.... loophole
What’s to stop a predatory, non trans Male just changing their name, getting a new identity and failing to disclose? Add in a climate of fear over deadnaming and that loophole widens.
When people can’t ask the hard questions, that loophole becomes big enough to drive a bus through.
This isn’t about being mean to trans people. It’s aboit safety.
