I'm broadly in agreement with Simster here. One assumes the FA (probably taking direction from UEFA) have to draw a line somewhere, or everybody will be wearing stuff. The annual poppy debacle grates with me every time.
I notice most appear to be on Guardiola's side re this issue. To play devil's advocate here: what would be the views on this subject if- entirely hypothetically!- James McClean turned out for a match wearing some sort of ribbon commemorating the IRA hunger strikers, or a Sinn Fein emblem?
Freedom of speech- or nothing to do with football?
I will just leave this photo of James McClean's leg here.
