To all of you EDM CDJs using, who can't mix by ear, relying on the SYNC button DJs: Stop offering your unsolicited opinions on the "limitations" of the genres that DJs who like to scratch should or shouldn't explore. An opinion about scratching lacks merit if it comes from someone without experience in that area. In addition to practicing the art of DJing, many of you EDM DJs should also work on the art of having an informed opinion before commenting on a DJ style you don't fully understand.
