The Gay Thread

[SzczerbiakManiac]

Help me understand this GLAAD Call to Action:

On the June 22 broadcast of ABC's daytime talk show "The View," host Sherri Shepherd and guest host D.L. Hughley perpetuated dangerous myths about African American gay and bisexual men.

While discussing the FDA's ban that prevents gay and bisexual men from donating blood, Shepherd and Hughley communicated misinformation about the causes of increased HIV rates among African American women and used the phrase "down low" to describe men who have sex with men but publicly identify as heterosexual.

I get that they're wanting a correction about the misinformation about AIDS infection rates. What I don't understand is the objection to "down low". What's the problem there? Is "down low" now a pejorative?
