I'm sure men like Kronke have put up with much worse in their lives. I don't see him selling his shares because of a chants and boos. No idea what would make him go besides more money being thrown at him or if the clubs finances started looking a bit risky. I'm not so sure about Kronke's influence on the club to be honest because he knows very little about football and Wenger is the man with the vision. But that's another debate. This is why I say an outright boycott for the odd game is a clear message.
