Parkland shooting survivor David Hogg sparked a revolution against Fox News host Laura Ingraham on Wednesday night, after she criticized him for "whining" about not getting accepted into four colleges to which he applied.
The conservative TV personality -- who was similarly slammed for telling Kevin Durant and LeBron James to "shut up and dribble" earlier this year -- has been called out by Avengers Chris Evans and Don Cheadle, "Guardians of the Galaxy" director James Gunn and celebrities including Alyssa Milano and George Takei.

Her tweet was in response to an interview Hogg did with TMZ, where he said, "It's not been too great for me and some of the other members of the movement ... it's been kind of annoying having to deal with that and everything else that's been going on but at this point, you know, we're changing the world. We're too busy. Right now it's hard to focus on that."
Hogg responded to the message on Wednesday night with a call to action, asking for a boycott on her advertisers. His tweet has generated 28k retweets and 59k likes in just 13 hours.
