I doubt I will support Inter anymore after this
I doubt he'll stop supporting his team if he loves it, but I won't blame him if he feels betrayed and loses interest.
You know, the Inter fans went through some very tough period (not winning shit for almost 2 decades) and when Calciopoli happened they really thought that they were being robbed and cheated over the years. Can you blame them? All fans would have behaved the same way.
So now if it's proven that Inter cheated too, it will mean that they indeed sucked over the years, they won't be able to feel like victims anymore and there will be doubts over everything they achieved even after Calciopoli. They will feel betrayed.
Just like it was with the Juve fans. Some loved the team too much and weren't capable of seeing the negatives. We were protective like a mother over her child, even when the child did wrong. But some of us felt betrayed and stopped following Juve and serie A anymore.
