Lord Bhattacharyya's "Chamberlain" speech continues to make waves.
And naturally the focus was on his somewhat unflattering comparison between the achievements of Joseph Chamberlain and those of today's municipal leadership under Mike Whitby.
Personally, I have thoroughly enjoyed the debate that followed. It is the sort of open discussion we should be having on many other things – bravo, incidentally, to Clive Dutton, Birmingham City Council's chief planning officer, for demanding design improvements to the sticking plaster makeover of New Street station. Debate is how you get ideas, leadership and dynamism to the fore.
Not artificial "One Voice" cartels and cabals.
But the "Chamberlain" line – despite the fuss it has stirred up – was just a strand of a speech which in some ways was far more controversial in its analysis of Birmingham's cultural mix.
For one, Lord Bhattacharyya came down firmly in favour of making sure religious schools are integrated, an issue the Government now appears to be bottling.
He stated: "There's been a big debate about Britishness. To me the debate is misguided. We are all British. We all need to be part of the same community.
"The last thing I want to see is a new community arriving in Birmingham and then cutting itself off – or being cut off – from the wider community that the city has to offer."
And I agree with him. Indeed I would go much further, abolishing all religious schools.
Religion should be a matter of personal conscience and not mass indoctrination.
Schools should be entirely secular with study of the world's religions taught as dispationately as a maths lesson. If people want to be religious, then fine. I would class myself as religious, though not overtly. But it should be in your own time.
Religious schools are divisive and disruptive.
But Lord Bhattacharyya also had salient words on the balance between majorities and minorities.
He said: "Let's not pretend that the mixing of communities is simple, or easy, or painless. It isn't.
"Many of these communities are blighted by poverty. Nobody is owed a living in this world, yet when we see deprivation, we must do our best to stop it."
He went on: "I want to see Asian, black and white lads playing football in the parks, not Asian lads, black lads and white lads.
"The best way of dealing with separation is to encourage integration. To me, multiculturalism must be about integration, not assimilation. The danger is that, in showing tolerance to minorities and their culture, one can appear to have less respect for the culture of the majority.
"Our tolerance for minority attitudes and cultures should not be abused by minorities wanting to impose values on the majority. That means avoiding separatism in our welfare, health and, especially, education systems. So I do not endorse or support exclusive religious schools."
These are absolutely vital issues for both community relations and the future prosperity of Birmingham.
