I was gonna say did someone call the fun Police? Then realised you are the Police.
I hear what you're saying but it's catch 22 because those rivalries are what makes the atmosphere at football stand out compared to Cricket, Rugby, any other Sport!
I do miss the Gills games but to be honest I'm not sure a 2,000 capacity with no away fans, social distancing, arriving very early before kick off, staggered toilet times, potentially having to wear a mask in the ground? will get my juices flowing. I could actually wait a bit longer for some more normality at football grounds but will be pleased for those Gills fans that do get tickets after such a long wait.
