When Krewella singer Jahan Yousaf penned an op-ed for Billboard that sarcastically concluded Deadmau5 saved Yousaf and her sister, Yasmine, from “doing porn,” you knew mau5 (real name: Joel Thomas Zimmerman) would swing back with a vengeance.

The world-renowned DJ attempted to swat away Yousaf’s claims of sexism within the industry with several angry tweets (while seemingly ignoring the overall message of Yousaf's op-ed, which outlined the dangers of hate speech on the Internet).

Zimmerman also posted several NSFW tweets, including:

of course that f---in idiot would play the sex card.... get the f--- out of here. please. just go.

the list of talented women in EDM is LONG. What is this? why is this a discussion? its f---in 2014 btw.

so @krewella you can take your 1920's smear "sex card" campaign and shove it up your f---in ass.

The Yousef sisters were miffed at the response, given the fact that most of the Billboard op-ed focused on not spreading negative messages on the Internet.
