I think the implication is that while, even as younger members of that society are figuring out what the root of the problem is, that the departments supposed to be helping with this are too fearful of saying so, for fear (real or otherwise) of being labeled racist/prejudiced.

I'm slightly surprised it's not obvious to you but giving you the benefit of the doubt: if we had had more open discussion/education about the horrible effects cousin marriage can have it might have helped change attitudes in the Pakistani community, but this was apparently resisted due to cringey PC fears about saying anything that might offend said community; the latter evidently a completely legitimate fear given the weaponising of offence by the left. If you still dispute what I'm saying, I'm far from the first to say it - below is from 2005:

'The Labour MP Ann Cryer has called for British Pakistanis to stop marrying their first cousins... Speaking to the Guardian, Ms Cryer said: "I'm not calling for a ban or a change in the law because that would mean changing the law for everyone. I'm simply calling for an enlightened debate. We've avoided discussions on this subject. People are being politically correct.'

> given the weaponising of offence by the left.

Is this left versus right thing? I note that the quote you provide comes from a centre left source.

It really isn't. The "right" has been doing the exact same thing for ages. See the weaponization of anti-semitism allegations by the Republicans (against Ilhan Omar most recently) or Tories (against Corbyn and Labour in general).

It's not a new phenomenon. Before racial/ethnic issues came to the forefront, partisans used religion and other relevant ideologies.

> weaponization of anti-semitism

Labour is the only party apart from the BNP to be investigated over allegations of racism by the Equality and Human Rights Commission.

A fact the Tory media, politicians, and supporters (case in point?) repeat incessantly, despite it being a Labour party matter. That's weaponization.

> despite it being a Labour party matter

This is an internal matter and has no bearing on who might be leading the country in a few weeks and voters don't have a right to know and the Tories don't have a right to point it out? Ok then.

And she was the exception that proves the rule.
