It's been answered many times but each time you've stuck your fingers in your ears and gone "la la la la la la". Hence why you get laughed at so much on here unlike other Pompey fans.
Actually I'm going to use some of your logic, I'm going to pretend Pompey never won the FA Cup. All the TV coverage, the tens of thousands of fans who attended the 'final', and all the teams you beat along the way were all part of one big conspiracy. No matter how much the local and national news report it I'm going to pretend it never happened and it was entirely a coincidence that thousands of Pompey fans decided to go and do some sightseeing in London, all on the same day
