The problem with all that, is it's so subjective. Take away the aspect of whether certain songs should be at the football, some folk would argue that comment on the IRA isn't sectarian or discriminatory, but political. I certainly wouldn't take any issue with someone singing against the IRA, but it appears FARE would act out against that.
There simply needs to be specifics from them, this vague, make-it-up-as-we-go-along tactic from them is an utterly unacceptable way to rule. At least if there was a specific set of "values" across the board, then the clubs would have no recourse for appeal if found guilty. As it stands, we could rightly assume that X, Y and Z are banned and refrain from indulging in such, but along come FARE and retrospectively decide that W is also unacceptable, and we're now in trouble for something else that we didn't even consider a problem.
Could you imagine a real world where the authorities didn't tell you what was and wasn't legal? It would be absolute anarchy if folk were left to decide what they thought was and wasn't acceptable conduct. We all come from different backgrounds and as such, our ideas of morality will differ from person to person. It's just madness.
