As any LGBTQ person can tell you, Pride events always have their anti-gay protesters. But at London Pride this weekend, actor Jesse Eisenberg slammed homophobic groups shouting discriminatory remarks over a microphone.

Eisenberg — who is perhaps best known for his performance as Mark Zuckerberg in the 2010 film "The Social Network" and is currently in England performing in his play "The Spoils" — can be seen in the video walking his bike along the Pride parade route. He comes across the protesters, who are holding up signs with Bible verses while preaching against the LGBTQ community.

When the group tries to give him a pamphlet, he refuses repeatedly, visibly shaking his head at the protesters. At this point, one of the group members can be heard asking him, "Is your mind closed?"

Eisenberg's response as he walks away is priceless. "Is my mind closed?" he retorts. "Dude, that's so fucked up."

This isn't the first time that Eisenberg has spoken out on behalf of the LGBTQ community and other minority groups, either.

In an interview with The Guardian published this weekend, the American actor told the paper that he was raised to support social issues.

"It was totally understood, growing up, that we should support people who are struggling. This was not debatable," he said.

We can't speak for the London Pride protesters, but his answer seems perfectly open-minded to us. Watch the entire interaction in which Eisenberg shuts down the anti-LGBTQ group below:
