Spot on - this will all fade in time.
I for one tried to ignore it all, but then again I was not going to every home game because of where I lived (Scotland). I have seen more Saints away games in the last 10 years than home so I got a different perspective of it all ie emotionally one step removed. I am now back in the south and in a position to once again go to home games on a regular basis, so I will be buying a ST for the first time, even though I have supported Saints for 41 years. Coincidentally, my ability to start attending regularly at SMS actually coincided with the exit of Lowe, and seeing the significant upsurge in crowd figures for the last 3 home games showed the real underlying support waiting to return.
You can say what you like about RL, whether or not he was wholly responsible etc etc, but his arrogant and condescending PR style is not up for question and it is, IMHO, that, more than anything which drove many fans away, albeit temporarily, from the club.
