"You're not interesting because you went to a high school where kids got shot. Why does that mean I have to listen to you? How does that make you interesting? You didn't get shot, you pushed some fat kid in the way!"
Actually, Louis C.K. got it wrong; Hogg wasn't even at the school when the Parkland shootings occurred. He did, by his own admission, subsequently hop on his bicycle and pedal over there afterward. And media still refer to him as a "survivor".
Unsurprisingly, a lot of folks crawled out from the baseboards to express their "outrage" over the comedian's take on the "survivor". In some respects, C.K. reminds me of Carlin, who routinely "outraged" people in his later years.
