AceShowbiz - Model-turned-actress Emily Ratajkowski finds it "exhausting" constantly having to defend herself from haters online, especially when she speaks out on social justice issues.

The "Gone Girl" star is fed up of dealing with those who feel it isn't her place to comment on topics like feminism or gender equality, because they don't think she's smart enough.

"It is super hard to constantly be dealing with negative comments about how I'm a bimbo and I should keep my mouth shut," Ratajkowski said at TheWrap's Power Women Breakfast in New York City on Tuesday (July 09). "That's exhausting."

Asked if she's developed a thicker skin in the wake of the criticism, she revealed, "I try to. Sometimes it really sucks."

The 28-year-old has become known for using her platform to address causes she feels passionately about, and in May, she posted a provocative shot of herself on Instagram to protest Alabama's controversial new abortion ban.

"This week, 25 old white men voted to ban abortion in Alabama even in cases of incest and rape," she captioned the image.

She added, "These men in power are imposing their wills onto the bodies of women in order to uphold the patriarchy and perpetuate the industrial prison complex by preventing women of low economic opportunity the right to choose to not reproduce."

Ratajkowski also made her feelings felt last year when Judge Brett Kavanaugh was nominated to the U.S. Supreme Court after he had been accused of sexual assault. She was so furious about the allegations, she was even arrested alongside Amy Schumer at a protest against the judge's appointment in Washington, D.C. in October.
