Tomic doesn't deserve his place on the tour IMO. He is an awful image for the sport: terrible, punk attitude with little, to no respect for his peers. And tennis that really speaks volumes of putting in a shit effort. The fact that our own Aussies are slamming him says alot. Any punishment that is laid on him, he deserves it.
Let's not get carried away. It's not really up to anyone to decide if he deserves to compete or not. If we went down that road you could easily kick out half the players. Get's his ranking makes the main draw, that all that matters in that regard. He nor any player is in a popularity contest to decide if he should be allowed in or not.
That said, it's very clear Aussies were embarrassed by him on the world stage and hence the anger. You really shouldn't worry so much about that. No one outside Australia even knows the kid anyway.
