In the same way you can't call it based on one event, you can't judge a game and completely gloss over the biggest moment in it to suit your perspective.
Anyway, a draw it is in the end; no matter what bad calls lead up to it. We'll move on.
Not glossing over it at all. After the bad call, Liverpool could have easily ended up leading into halftime 3 - 0 up but for some brilliant Cech keeping and scrambling (in the best sense of the word) Arsenal defence. But it didn't.
A majority of the football media called the game Liverpool's way afterwards and that we were unlucky yet I'm tending towards the 50/50 as mentioned. I think both teams were lucky and unlucky. A 0 - 0 draw of that quality will always throw up discussion over 'who bossed it'. Both teams did, in different ways and for equal portions of the game.
