Kick-Ass star Chloe Grace Moretz has said she will not tolerate anti-gay bullying from her fans as two of her older brothers were “treated horrifically” with homophobic abuse growing up.

The US actress, who regularly keeps in touch with fans on Twitter, told Seventeen magazine: “I have two gay brothers and two straight brothers, and my gay brothers were treated horrifically until they grew up and understood how to deal with it.

“I will delete you and I will block you, and you will not be a part of my life if you ever say anything bad about my brothers.”

She added: “Never choose your friends over your family or a boyfriend or girlfriend over the family.

“My mom has always taught us that blood is thicker than water. No one will ever understand the dynamic of your family. Ever. We are the closest family ever and we are the most insane family ever. It may look weird to others, but to us, it’s life.”

Recently, Outspoken equal rights advocate and Hollywood actor James Franco responded to rumours and jokes about his sexuality, saying “I wish I was gay” because being gay is “awesome.”

British-born American actor Wentworth Miller also revealed this month that he attempted suicide at 15 by swallowing a “bottle of pills” because he was gay.
