"You shouldn't be concerned that sex offenders are in wrestling now because there's always been sex offenders in wrestling" has always been an.....interesting.... argument to make. I mean, maybe it's a pipe dream to dream of a world where there's no sexual predators in wrestling, but maybe it's not the worst thing to strive towards?
Also, Kenny needs to realize he's the public face of a major company trying to make inroads to the North American market. Fair or not, it's going to reflect on him and/or New Japan when it comes out their champion was on a show with a sex offender. Part of being the TOP GUY involves doing due diligence for shit like this.
