During Sunday's show, McGowan replied to a tweet from friend and fellow Harvey Weinstein accuser Asia Argento, which read, "No one should forget that you were the first one who broke the silence. Anyone who tries to diminish your work is a troll and an enemy of the movement. You gave me the courage to speak out. I am on your side until I die."
"And not one of those fancy people wearing black to honor our rapes would have lifted a finger had it not been so," McGowan responded. "I have no time for Hollywood fakery, but you I love, Asia Argento."
But this isn't the first time the leader of the Rose Army threw shade at Hollywood stars for choosing to show their support for sexual harassment and rape victims via fashion.
Back in December, when McGowan heard about the Globes' all-black theme, she tweeted, "Actresses like Meryl Streep, who happily worked for The Pig Monster, are wearing black the Golden Globes in a silent protest. YOUR SILENCE is THE problem. You'll accept a fake award breathlessly and affect no real change. I despise your hypocrisy. Maybe you should all wear Marchesa."
After McGowan's tweet went viral, Amber Tamblyn called her out on Twitter, saying it was wrong to bash the way others choose to create change.
Argento then tweeted at Tamblyn, asking her why she called Rose out in a public forum and not in private.
To that, Tamblyn responded, "Her statement was public and hurtful to some women, so a public response was earned. I spoke to her at length today. She knows how I feel. I love Rose fiercely. That will never change. To be critical of an action is not to condemn the person behind it. There's your common message."
