I did hear about this alleged incident that happened in the block I was sat in, as I did not see any other altercations, presume this is what you are talking about, if not I apologise.
From what I was told your father repetadly did not sit down as Argyle fans requested, this caused an altercation.
People behind shouted to him to sit down, to which he replied to some fans, he allegadly said to one fan come down here and say that, which the argyle fan did, hence an altercation, I personally saw your dad arguing gestering to the argyle fan.
I am not accusing anyone of any offence, I am just giving the other side of the story. It could have turned very nasty as there were no stewards or police near by, it was Argyle fans that calmed the situation down, your dad was lucky, very stupid at his age to get up and celebrate in any home end, would you have done that at Bristol City - NO so don't do it here.
I know its very sad we cannot all get on, but who was in the wrong end, your dad, if he was not there he would of allegedly not been hit.
I would never go in the home end at Bristol Rovers, as I know it would cause touble.
