Jessica Chastain is using her voice to put the harassment LGBTQ YouTube users face into the light.

It started with a thread by Vox writer, Carlos Maza about the continued attacks on his “sexual orientation and ethnicity”.

“I’ve been called an anchor baby, a lispy queer, a Mexican, etc. These videos get millions of views on YouTube. Every time one gets posted, I wake up to a wall of homophobic/racist abuse on Instagram and Twitter,” he wrote.

He adds he is “not mad at Crowder.” As there “will always be monsters in the word. I f**king pissed at YouTube, which claims to support its LGBT creators, and has explicit policies against harassment and bullying.”

“The problem is that YouTube is designed to give those a**holes a megaphone, push new followers in their directions, and keep them listening. It’s a weapon.”

Chastain retweeted the thread, tagging her friend and YouTube’s head of fashion and beauty partnerships, Derek Blasberg. “I’m hoping that your open heart and platform @YouTube can stop this targeted harassment of the #LGBTQ community. Love you,” she wrote.

According to Just Jared, YouTube is investigating Crowder’s videos since the thread went viral.
