I find it strange that folk like you and Lionmo hate Celtic more than your teams City rivals. I'd say the exact same to someone if they hated Rangers more than their main City rival as well.

Loads of Hearts fans hate Celtic more than Hibernian, this goes back a long time to the 70s and 80s. I also don't live in Edinburgh so I rarely meet any Hibs fans to build up a proper hatred. I still love beating them though, just for the GIRFUY factor.
