Firstly I think you mean Petty, secondly I think you mean Hull RLFC, we are HCFC. Your ignorance is embarrassing.
You also rather miss the point of this thread. We are not feuding with them, we're actually pitying them. I am genuinely sad that Rugby League is going down the pan, and I wish them well, but they will not save their game by pretending its woes are related to football in general or Hull City in particular.
Rugby Union has learnt to co-exist with football (Leicester City and Leicester Tigers) even though one of those is a top flight professional sports club and the other is struggling to escape mid table mediocrity from the second tier of their sport.
