Ruffalo protests at Trump Tower over Virginia violence

The 49-year-old actor decided to protest following US President Donald Trump's response to the violence against the counter protesters of a rally organised by white nationalists.

Trump had said that "there is blame on both sides" for the demonstration that turned violent on August 12.

Ruffalo posted a video on Instagram to inform his fans and followers about the protest.

"We want him to hear us. We want him to know that an American killed on American soil by a Nazi is not acceptable. That there is no equivalence, there is no many sides.

"There's two sides to this. People who fight Nazis and Nazis and that's it. We cannot allow Nazis to be a normal part of our society. We have to fight," he said in the video.

The Avengers star was supported by filmmaker Micheal Moore, who interrupted his own Broadway show, 'The Terms of My Surrender' to sit beside Ruffalo on top of a double–decker bus he arranged for the public. The vigil was also joined by actor Olivia Wilde, who led chants of "Trump is not a legitimate president! Trump is not America! We love America!" outside the tower.

According to Entertainment Weekly, The Big Sick actor Zoe Kazan also came forward to raise slogans such as, "We reject fascism! We reject white supremacy! We reject Neo- Nazis! We will not accept white supremacy in the White House!"

Some celebrities took to social media to register their protest.

TV host Jimmy Kimmel wrote on Twitter, "I haven't seen anything that crazy since Tyson bit Holyfield @realDonaldTrump."

Author JK Rowling tweeted, "One good thing about that abomination of a speech: it's now impossible for any Trump supporter to pretend they don't know what he is."

Veteran actor Barbra Streisand said Trump said what he really believes without a prepared statement. "Equating neo-Nazis to those protecting civil rights is disgraceful and crazy," she continued.
