Can I change my caste?

Of course the OP didn't invent the Caste system. I've no idea why you'd type that.

Ummm. No caste is based on actual ethnic differences, proven by linguistic and genetic studies. It’s not comparable to gender which has zero biological basis:

As are lots of things, I don’t think the op invented the caste system.

The Indian govt has measures to try to level up the people from the oppressed castes. It knows that abolishing castes on paper doesn't work, they continue to operate in practice, so it does the next best thing of trying to uplift the members of the oppressed castes. The certificate is to stop people from non-oppressed castes from identifying as a member of an oppressed caste to fraudulently claim levelling-up measures.

The parallels with white people identifying as Black and men identifying as women are clear.

What is it about the Caste system that you want us to have in the UK?

The Caste system is about keeping people down, not self ID. It is a classic, sexist, patriarchal system that hurts women most.

No matter their achievements, they will never escape their less than human, or even animal, status.

Should have the same over here, in the UK.

No it doesn’t and the OP is not arguing that it does. The point is about self identification.

It doesn't make up for them being beaten, raped, murdered and enslaved, with impunity by other, "higher" castes. You might as well say the Taliban have got it right with their enforcement of single sex spaces.

It's not done to protect women. It is enforced as subjugation of, mostly poor, women and children.

I would love to identify as retirement age and claim my state pension. Why not?

I always find the best comparison to be age. Because it's very possible to 'feel' 20 years younger. In fact our feelings will be much more reliable given we will have actually experienced it. Its also much more scientifically justifiable given its possible to have a biological age less than your chronogical age. I've yet to have anyone explain why we can't self ID our age and we can our 'gender'.

The enforcement of the Caste system in India does not protect the rights of oppressed classes. It operates to stop people from identifying out of oppressed classes to become actual human beings with fundamental human rights.

OP might be, and I would agree that sex should not be something that governments can just pick and choose and name for yourself.

I think its more just the example of how made up things are treated compared to real things.

Its an interesting point

We could add into the discussio, which I know has been mentioned countless times on this bit of the forum, why you cant self identify your ethnicity. Why is that socially inappropriate? (given that ethnicity is no one thing in any case)

I get that both the Caste system and trans agenda are damaging to women. But the OP seems to be criticising(?) the UK government for not acting more like Indian government's enforcement of the Caste system.

Caste is as real as gender. Meaning it’s not real; it’s a set of made up rules based on outdated concepts and stereotypes. Sex, however, is real, it’s a biological fact. Caste and gender are made up nonsense concepts, sex is not. Can you not see the comparison?

The caste system is destructive and very damaging to women.

So is the trans agenda.

The OP is making a valid point.

I suppose the point is that another government has made a decision that a made up thing like caste, cannot be changed, its immutable.

Sex, which is not a made up thing, is apparently mutable. According to the UK government

It may not be comparing like with exact like but I get the point.

The point is that govts can and do say "no" to people who want to identify into and out of oppressed classes. The UK govt is simply choosing not to say "no" to men pretending to women.

The Caste system is destructive and very damaging to women.

I don't understand your point.
