The aspects to the "institutional racism" as, whilst you say that the "club" as it is purely bricks, mortar, etc. it is the people, the policies, how individuals behave and are expected to behave.
The fact that they would allow such recognised behaviour meant they either didn't have the correct policies and processes in place, or that the reporting of such behaviours were not able to happen as they were not dealt with appropriately and the systems in place did not do anything to stop this.
I do believe this is more wide-spread than just Yorkshire, and it does go back a long way, not that this is an excuse but I just do not believe the club has moved with the times.
To try to explain the "it's not bricks and mortar" bit, if there is a massive oil spill in the pacific ocean while BP are transporting this across the world, the news would be "Large BP Oil Spill", it wouldn't be "Dave the Sailor Spills Oil". It is the responsibility of the company to make sure the right things are done at the right time.
