I do not hold those reactionary views, and the statement carries no stigma.
What is your correct, PC ending to the sentence,
"The difference between general population UK, effectively zero prevalence, and the MSMs and African born, is ....." ?

Fair play to you for withdrawing your earlier assertion.

De Cock said "very unlikely" and said there is "no generalised epidemic"

"No risk to heterosexual population" should read "Except for high risk groups, there is negligeable risk to heterosexual population."

Behaviour and practices. De Cock says it is "important" Why should I doubt him?

"minorities suffering most with HIV are not suffering because their behaviour is "worse" or "less good" or "more risky" than the behaviours of others"
I would have to leave in "more risky."
