This is very sobering

This is only a partial aspect of the article, but I beg to differ with this particular reasoning:
"Decades into the epidemic, scientists have made enormous strides in unlocking the disease at the molecular level. Understanding why HIV has taken hold of black America and how to prevent its spread has proved to be no less daunting a challenge. The root of the problem is poverty and the neglect that comes with it—inadequate health care and a dearth of information about safe sex. IV drug use, sexually transmitted diseases and high-risk sex (marked by multiple partners and no protection) have fueled transmission; homophobia and religious leaders steeped in moralistic doctrine have suppressed honest conversations about how to stop it. All the while, much of black leadership has been slow in responding, only recently mobilizing to protect its community. "
The blame doesn't lie with any third parties who did not participate in the sexual act as part of the transmission.
