2 witnesses: Bowie Himself, and his wife.
And, to repeat, it’s not about convicting anyone of anything. It’s to connect to the earlier demise of those who engage in MSM.
In any case, this book, evidently tells more:
Neither Bowie nor Jagger has ever confirmed the naked in bed accusation.
Still just one witness.
David Bowie was a 70’s and 80’s rock star who engaged in the behaviors that you would expect of a 70’s and 80’s rock star. Take it or leave it.
Without looking at his medical records and getting his physician’s notes on his cause of death it is impossible to know if his sexual promiscuity led to his death. He also was a chain smoker so perhaps it was lung cancer. In scientific arguments correlation is not causation. A person who has cancer can still die in a car crash.
Men who have sex with other men have a shorter life span and are at risk for a host of diseases that heterosexual monogamous men are not. Keep in mind however when false conclusions are drawn because of faulty logic ( Bowie had gay sex so it must be the sex that killed him) and are proven wrong, it only weakens your case.
