IANAL but I’m fairly sure people are also protected in (UK) law under the characteristics of gender reassignment.

Yes there are 9 protected characteristics: age, sex, race disability, belief etc and gender reassignment. Gender reassignment does not mean a person's sex has changed. People should not be discriminated either because of belief or gender reassignment or sex.

Correct. Surgery is a personal decision. What the EqA says is that a person shouldn't be discriminated against because of transitioning (in any way) eg they should lose their job, or be treated less favourably at work. It doesn't mean their sex has actually or legally changed.

Let’s say we just accept that bit so we can let it go; how is it related to “the legal case that argues 'gender critical' views should be protected in law”?

"Religion and belief" is a protected characteristic. You should not be discriminated against or harassed at work or as a customer/service user etc... because of your belief or lack of belief

Only beliefs worthy of protection in a democratic society. I genuinely cannot wait to hear the argument that beliefs against human rights are worthy of such protection. But @Docstockk clearly disagrees that any beliefs are worthy of protection, so popcorn out for the GC wars.

Lol. I don't think so. The fact that belief in islam or christianity are covered by the Equality Act does not mean that these beliefs (or others) should be the basis for other legislation.
