An elderly social justice warrior traveling on a train in Japan has seen fit to carry out punitive measures against a woman taking up too much space through the act of crossing her legs by whacking her with some form of antiquated reading material.

Witnesses believe the reading material used to maintain social order was made from paper.

The manspreader chivalrously took on the role of social justice vigilante despite telling train staff he is “busy” and has “things I need to do”.

The man said he was “not assaulting” the woman, he was merely hitting her with what he described as a “newspaper”.
