We are human beings.</s>UNIDENTIFIED MALE: He's taught me a lot of things about AIDS. He's taught me not to give up with your life. Fight for your life.</s>JOHNSON: I don't hide my sick.

He was very bold about it, and he attached many hearts.</s>JOHNSON: He would like to be remembered as someone who motivated an acceptance of infected people.
