I somehow doubt that the baroness has much experience of being discriminated against.

Regardless, I fail to see the how experiencing discrimination is any real benefit, it is not generally considered valuable for a rape expert to have actual experience being raped, why would it here?
In fact I would think of it as a disadvantage as it is hard to imagine a victim being objective enough for effective decision making.

But that of course assumes that the baroness by the virtue of being non white has any meaningful experience of being discriminated against which, as our mentally challenged American Indian friend has noted, would be somewhat of a problematic assumption.
