What is inaccurate about the claims. The English are an ethnic minority in London. That is a fact. You can say oh Englishness isn't the same as the Ethnic English, but to do that you are stripping English people of their ethnic identity and their culture.
> nobody says he shouldn't have the right to make such claims
Yes, please do believe that. Lots of them. It may shock you but in much of the world there isn't free speech. Imagine that. Do you think in China you can go around criticizing the government?
> people have less tolerance for such inaccurate and unfunny claims and will call him to task for such nonsense is a bit silly
No, they are claiming the speech itself is unsafe and trying to cancel people. There is a huge difference which you don't seem to get. And it's not silly. It's primarily about intimidation and fear that if you say the wrong thing you will lose your job, get cancelled, ect. Tolerance to intolerance is not tolerance.
I sometimes wonder, do people who think like you actually know how many people died in the so called "cultural revolutions" around the world (such as in China and Russia) which happened during just the last century. It's in the tens of millions. Intellectuals and dissidents rounded up to be killed or put in gulags. People forced to pledge loyalty to causes and leaders and to be re-educated.
The cultural revolution leaders in our country have already started to get rid of any kind of meritocracy (racist tests they claim). UC schools functionally banned the tests just recently. My brother was telling me that UCSF med school removed standardized testing from its admissions and in one year the Asian population went from 60% to 20%. Across academia now your ability to get in will be based on your ability to show how you contribute to the goal of diversity (via skin pigmentation of course).
But I guess to some it's all silly.
https://en.wikipedia.org/wiki/Ethnic_groups_in_London
63% of London was born in the UK. You mean white English, I presume? Even there, they're a plurality.
That’s pretty clearly not true, though the boundaries of that ethnicity will be perceived differently by different people.
“The English people are a nation and an ethnic group native to England who speak the English language, and share a common history and culture. The English identity is of early medieval origin, when they were known in Old English as the Angelcynn ('family of the Angles').”
Engaging ideas on their merits isn't the same as engaging them in a vacuum.
