I'd say it goes deeper than that. When we lost the FA Cup final in 68, the RS fans in my mums Street had a street party, and taunted my then 8 and 6 year old uncles as they sat on the step, heartbroken. Grown men taunting children who were upset. Don't let anyone tell you it's a recent thing. It's literally been that way for decades because they have been bitter about us for as long as they have existed, but will never admit to it. The Hughes Incident is just indicative of a pattern of behaviour that stems from their own bitter, twisted, narcissistic jealousy.
The irony is, they actually try to trot out the line "It just means more". They don't even realise the irony. To be sure, they will never be be happy, never be satisfied. Constantly looking over their shoulders and stomping their feet for attention and adulation as everyone else cringes at their behaviour.
Just be glad that you are a blue. We may never have the same level of success as them, but everything we achieve will actually mean more.
