AP article on Red Cross accepting blood

I have asked about this situation when I give blood at the Red Cross.  I especially appreciated the part of the AP article that talked about how inviting friends to come with you to give blood might not be appropriate in terms of the questions they are asked about their past sexual behavior.  I was surprised by this statement from the FDA:

"According to the FDA, men who have had sex with other men represent about 2 percent of the U.S. population, yet accounted for at least 61 percent of all new HIV infections in the U.S. in 2010."

How does this statement compare to the general public myth of 10% of the population being gay?
