During the rock band's performance at Kansas City Rockfest 2014, Lewis noticed that a group of men were taking advantage of young girl who was crowd-surfing. Mid-song, he couldn't tolerate it anymore and decided to do something. He proceeded to chastise the men in a #NSFW rant, which ended with him telling the girls: "Now girls, feel free to crowdsurf safely." His blusters were met with cheers from the audience.
As someone whose crowd-surfed a few times in her day, I appreciate this bold admonishment — especially on the heels of Iggy Azalea's outspokeness on the issue. Just last month, the Australian rapper revealed that she has to take precautions when crowd-surfing during her concerts due to fear of being assaulted.
