If you are going to shoot your mouth off on a public forum then you should have nothing to hide.
It doesn't matter one jot if York fans have posted this message on other forums - if Skeggy wants to provoke people then it SHOULD come back to bite him on the arse.
If you're saying this because you're embarrassed at one of your fellow 'fans' then GOOD. However, according to fans in the Conference I have spoken to, they claim Boston fans were voted the most unpopular in the Conference last season by quite some way.

However, in the League you make more enemies, and they have longer memories.
