Antifa?
SPJNK
My guess is Pfeffer is nothing more than a spoiled narcissist. Hard to say if he has enough interest in the world around him to be Antifa. If there is such an affinity, it might be reflected in his social media. Given his youth and physical appearance, he may not have an easy time of it in prison. But, he should work on adjusting since that will be his life from this point forward.
