His SON trolled him? Even better! Which makes some sense, as otherwise why target Rick Wilson who is a pretty much nobody low-level unrecognized political hack?
The content is very much inline with the mentality of 4chan (anime, japanese porn, perversion), so that matches up too.
Rick Wilson was trolled with perverse writings of his own son, after taunting and condemning 4channers as juveniles masturbating to anime in their mom’s basement. His son didn’t troll him, but he was trolled with his own son’s perversity and it went straight over his head.
