We see that best on "Same Love" as he compellingly relates how when he was in the third grade he came to the conclusion he was gay because he could draw, kept his room clean and had an uncle who was in a same-sex relationship. His mother reassured him he was not, but it's still a discussion you won't find many other MCs leading, even in the post-Frank Ocean age.
Haggerty thinks the song's cultural impact shows how much the notoriously homophobic hip-hop world has changed in recent years.
"I hope we're part of that transformation," Haggerty said. "I don't think a song like 'Same Love' would have been received the same way even five years ago. We as a society and a culture have proven throughout time that we evolve, that we become slowly more compassionate and tolerant and accepting. The last couple hundred years in American culture have shown that. Obviously, there's give and take. There's times when we haven't and times that we lose ourselves, but I do think we're evolving as a society and hip-hop is a reflection of that."
