The person behind a Twitter account for the CW hit Supergirl proved to be the real hero this week by simply schooling a homophobic fan on love and acceptance.

Supergirl's adoptive sister, Alex, is a lesbian on the DC series, and an angry fan took to Twitter to complain about an intimate scene she had with her on-screen girlfriend.

“Please tone down the homosexual messages," wrote the viewer. "Used to watch this with my daughters, now I have to explain to a seven and 10-year-old, thanks.”

The concerned mother got a reply from the Supergirl account reminding her that it's actually the perfect opportunity to be a good parent and open her children's eyes to love.

“Good, explain to them that love is love and it’s beautiful no matter where you find it and who you can find it with," the account replied.

Meanwhile, the LGBT storyline has already proven to be comforting for struggling queer youth. A comic book clerk's story went viral on Twitter last year after she helped a depressed teen discover other comic characters who were in same-sex relationships like Supergirl's sister.

"For the first time, she didn’t want to die because she got to see Alex be amazing and be queer," the clerk wrote.
