That's such a bizarre statement. Diversity was rare in London? Have you ever been there (I lived there for years).

London is quite possibly the most diverse city in the world.

Edit: I thought perhaps New York might be more diverse, so I hedged but it turns out Toronto is! I would not have guessed.

I was talking about the past when the british empire still existed.

New york is also diverse but if you look at demographic data from historically not that long ago and are racialising then it really wasn't. Those shifts are recent.
