Fair enough that’s what forums are for.
In terms of evidence no smoking gun, just my observations - the general sanitisation of match days, pre match the absurdly loud PA system giving no chance for an atmosphere to grow organically, the heavy handedness of stewards to any kind of boisterousness - I was in 115 last season and the lads in there really put a shift in singing wise but stewards were constantly and needlessly asking them to not encroach on the aisles etc -, then we have the whole issue of the new stand being diluted by corporate areas, away fans being tolerated in home areas etc etc
