It's not just a Brighton fan thing though.He did. He was always backing into players and then falling over looking for the free kick.
I think the hate for Kane is purely because of that Lallana penalty. Before that I don't remember anyone saying anything about Kane. Since it he's been public enemy number one(well, 2. Zaha is number one in that regard) and because of that a lot of people now only see what they want to see. Namely that Kane is a diving, dangerous cheat.
That said I'd be delighted if he got sent off for diving today and this post was bounced with schadenfreuden glee as we whallop the ten men of spurs.
All the supporters of teams he's dived to win penalties against think he's a cheating twat.
That is to say, all of them.
