Ariana Grande: 'Homophobia is outrageous'

Pop star Ariana Grande has confessed she becomes a "raging lunatic" when she encounters homophobia.

The Problem hitmaker has been an outspoken advocate for lesbian, gay, bisexual, and transgender (LGBT) rights over the years as her half-brother, Frankie Grande, is gay.

Grande has now opened up about her ongoing fight to stamp out intolerance in a new interview for V Magazine with her Scream Queens director Ryan Murphy.

She says, "My brother is gay, all of my best friends are gay. When my brother came out of the closet, it wasn't a big deal for my family. Even my grandpa, who is like, super old-school, was like, Good for you! It's outrageous to me when I see people hate on someone because of their sexuality. I hate the intolerance. I hate the judgment. I hate it so much...

"It's something I'm super passionate about, because whenever I would see my friends get bullied, or my brother get hurt for his sexuality... I would literally become a raging lunatic because I just can't take it. When you see someone you love hurting, for such a superficial, bulls**t reason, it's like, how small and spiritually unenlightened and dumb as f**k can a person be?... You're actually judging someone as a person based on their sexuality before you even have a conversation with them?"
