Brianna Wu, a Democratic candidate for Congress, is best known as "a prime target of Gamergate," a sexist hailstorm that led her to receive hundreds of death threats for merely posting a meme on Twitter. So Wu understands the power of trolls on Twitter, and she has years of experience shooting them down.
That brings us to the United controversy, when United Airlines refused to let two young girls board a flight while wearing leggings. As internet outrage mounted at the situation, United defended their position. "UA shall have the right to refuse passengers if they are not properly clothed via our Contract of Carriage," they tweeted, over and over and over again.
They later seemed to pivot, clarifying that the travelers were "pass travelers," or family members of United employees subject to a stricter dress code.
Here's where Brianna Wu comes in, tweeting a reasonable defense of leggings.
