To be honest It was only embarrassing, not just to show disrespect, but our fans being racist, the "zingaro" thing and not to forget Balotelli's case too.
We were never racist, we never had a background or history with racism.
Zlatan was called Zingaro for obvious reasons and our fans had all the rights to call him Zingaro or even more. And don't even think he defended Juve, he defended his two titles that he won with us. He never defended the Club but he defended his own reputation with the two titles that we won.
On a serious note, it's funny how when our fans were calling Zlatan Zingaro couple of members got pissed but it's alright for them to make fun of Prophet and Islam. Contradiction at it's best.
As for Balotelli, I remember pretty well why he got booed and that's not because of his skin color, we never booed a black player, Balotelli was booed because he's one arrogant aka Ibra prick. He asked for it and he got it. But headlines after the match wasn't too nice, I'm sure white Balotelli was going to booed or Mexican or Arab Balotelli was going to be booed too.
