The 22-year-old singer is opening up to her Scream Queens boss, Ryan Murphy, in a Q&A for V magazine, in which she talks about being an outspoken advocate for LGBTQ rights. Ariana's older brother, 32-year-old Big Brother star Frankie Grande, is openly gay.
"I mean, here's the thing: I wasn't raised in a household where it was considered abnormal to be gay. So for me to meet people who use the word 'f***ot' as an insult, with a derogatory meaning, I can't take it," she tells Murphy. "I don't understand it. It's so foreign to me."
"I hate the intolerance. I hate the judgment. I hate it so much," she stresses. "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 become a raging lunatic. 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?"
ET actually caught up with Frankie at the 2015 Streamy Awards last week, where he shared his own thoughts on those judging him for his sexuality.
"When people come for my sexuality or family, that's the thing where I'm like ... and then you gotta realize, maybe they're having a bad day. You don't know. You don't know what's going on in their life, so ... I ask not to be judged, so I'm not gonna judge you," he told ET. "If you're gonna be filled with so much hate, then I think there might be something else going on in your life that you should address, rather than me."
Ariana also talks about being a super-fan of another outspoken supporter of LGBTQ rights during her chat with Murphy, the iconic Madonna. The "Love Me Harder" singer -- who says the 57-year-old legend has been very "motherly" to her -- reveals the two previously bonded over practicing Kabbalah.
"I practice Kabbalah as well, so that was one of the first things she mentioned, because I had my Zohar in my pocket," she recalls. "And we danced together at her Oscar party. That's all I can ever ask for. She inspires me endlessly. I'm so inspired by her fearlessness ... Like, 'This is me, and if you don't like it, go f**k yourself.' That's so cool, you know?"
The former Nickelodeon star has certainly faced her own criticism about her supposed diva reputation in the past -- who can forget her notorious donut-licking fiasco over the summer? -- but points out that she doesn't have to subscribe to just being "America's sweetheart." Ariana herself admits she swears like a sailor, and has sexual lyrics in her hit songs, but she's not about to apologize for it.
"I don't need to be a pop princess who is America's sweetheart or the next rebellious, wild, young thing. I don't need to pick or choose," she explains. "I can show skin and swear like a sailor, but also be a good role model. I think that I'm a good person. I don't think cursing makes you a bad person. I don't think showing skin or kissing boys makes you a bad person. I don’t think that expressing sexuality makes you a bad person at all ... I think it's great!"
"We need to encourage each other to do what we want and not let it totally define us," she adds. "The things that people think define them aren't valid either. You could see a girl who's completely covered head-to-toe and who looks like the sweetest little thing in the world, and she could be the most horrendous human being on the planet inside."
