While it’s clear there is a punch I wouldn’t categorize this as Bieber punching a fan. It’s more like Bieber defending himself from someone trying to grab onto and possibly jump into to his moving vehicle.
Too often these days celebrities are being accused of not being kind enough to fans when in reality these so called fans are aggressive people violating a fellow human’s space.
Look what happened to model Gigi Hadid in Milan during fashion week earlier this year. Initially, many accused her of being disrespectful.
Nobody has to be polite to someone who makes you feel unsafe.
Not a chance
