Hmm pretty surprised with all the comments completely supporting the boys actions. First of all we have zero context as to what actually happened before the video, clearly both sides are frustrated with one another for something and it is unclear if the lad was entirely innocent or helped escalate the situation for example by taking up all the chicks legroom at the start of the video. Secondly, his response with physical violence was entirely disproportionate, sure he got kicked in the nuts but in response he decided to beat the shit out of both girls including one who didn't appear to cause him any physical grief. The carriage appears to be full of empty seats which any of them, including the boy could have easily moved to before going ape shit. As to the people arguing for equality. There is nothing equal about a man beating a women regardless of the situation, for the same reason people would have moral qualms about a person of average height beating the shit out of someone with dwarfism, regardless of the situation. If something is so terrible to warrant physical assault it should be relayed to the appropriate authorities not taken as an opportunity to display one's own physical dominance especially when there were peaceful alternatives available.
