I can’t speak for others, but I certainly don’t deploy it to insult an entire fanbase or community. I use it as a reference point to any Liverpool fan who has the temerity to suggest that their club is somehow better than mine, as many frequently do. As a counterpoint, it’s crude, I’ll grant you, yet utterly effective. A set of supporters that was directly response for such a tragedy has fuck all to crow about and need reminding of their hand in an event that shamed English football when they do. Perhaps if they showed a bit more humility and contrition then your comments would have more merit.
In addition, the widespread and enduring denials of culpability from club apparatchiks and supporters alike are outrageous and frequently utterly comical (Chelsea fans, Belgian skinheads, ‘wall collapsing‘ (which actually saved a number of lives in all likelihood)) seriously invite derision. These pitiful attempts at deflection are a rich source of comic material which deserve to be mocked. People need to be called out on their bullshit.
That about covers it from my perspective.
