Censorship.
I said that the accusation of racism is used to close down debate.
As you say, it did not work here.

The risk of chromosome disorders increases to a maximum of about 1 in 21 at age 45.
The risk of genetic disease given in the BBC report was 1 in 10 for first cousins.
More than double.

I agree that the statement was neutral, but it was based on culture.
That makes it a racist theory by Lox's edict.
