Some may think that there are a multitude of sins but the only unpardonable sin is that of mixing Campagnolo with Shimano which will damn your soul to an eternal hell of multi use pathways that are populated with uncontrolled dogs and joggers who cannot hear you over their headphones.
One shudders to think of what an eternity of that would be like.
People are free to believe whatever they may but is the combination of disparate beliefs that truly angers our lord and saviour, blessed be his name.
