I'd love to see strict liability introduced but 3 or 4 clubs just wouldn't go for it, so it won't happen.
As a fan of Ayr, we've some songs that some find distasteful and we've a group of fans that like pyro (I don't mind either), if either of those were dragged in under strict liability I've no doubt that our fanbase would cease both instantly as neither are that important to those that partake in them.
I'm of an age where I along with the majority have sang bigoted songs, not because I was bigoted but because it was aimed at whichever of the ugly sisters we were playing, like most Ayr fans, I ceased that sort of thing many decades ago once I realised it was a load of shite and what it was actually about.
