I think it's the media that's made a big issue about it and made everyone aware. No surprises there then as they're just shit stirring as usual. It's the rag manager they should have asked about it as it was his fans who sang it. Just turned the football show on now and they've just mentioned it again.
I'll add what I said in an earlier post. The majority of fans who've been going to games for twenty years and more will have sung and heard things equally as bad. I remember being in the Kippax when headlines broke Stan Bowles wife had left him. He got shit loads of stick. "Stanley Stanley where's your wife?" Was the mild one. It morphed into "Who's up Stanley's wife, whose up Stanley's wife, every every fucking one!" He was one of our ex players as well. That was the late sixties/early seventies. It's fair to say football continued to descend into a dark place over the next few years leading to Heysel and Hillsborough. It then cleaned up it's act and on the whole it's a much more pleasant place to go now. Sure I think it's been sanitised and Disneyfied a bit too much but it's now the year 2025, over 50 years since the Stanley Bowles chants. For me chanting somebody's mother is a slag is unacceptable these days. If that makes me a wet wipe I'm happy with that.
