AIDS memorial--Why?

"A design that calls for a grove of trees reflected infinitely by 12-foot-long mirrors was selected today for New York’s first large-scale AIDS memorial."

The AIDS Memorial Park organization, Architectural Record, and Architizer have announced the winner of a competition to design a memorial for victims of AIDS and an education center in Manhattan’s West Village. Studio a+i of Brooklyn, N.Y. won the blind competition with a plan to surround an existing triangular park with mirrored walls and a grove of white birch trees. Architectural Digest, Jan. 30, 2012

Why do we memorialize this particular disease's victims, a disease which is mostly self-inflicted through promiscuous, indiscriminate sex and multiple partners? We don't memorialize death by smoking, drinking or over-eating, or driving too fast, or not exercising.

Men who have sex with men--MSM account for nearly half of the approximately 1.2 million people living with HIV in the United States (49%, or an estimated 580,000 total persons).

MSM account for more than half of all new HIV infections in the United States each year (61%, or an estimated 29,300 infections).

While CDC estimates that only 4 percent of men in the United States are MSM, the rate of new HIV diagnoses among MSM in the United States is more than 44 times that of other men (range: 522 – 989 per 100,000 MSM vs. 12 per 100,000 other men). CDC Fact Sheet
