Its just fans having a laugh, if you want a quiet polite crowd go watch golf or snooker
Ive been going since I was 4 years old and will be taking my kids when they are similar age, crowds are going to swear and make fun of the opposition, as long as its not racist or homophobic or sexist then no harm done imo
Also, a tip for those who dont like rowdy crowds, dont stand at the back of the south stand, even half way down is much more timid
JP specifically mentioned the south stand atmosphere as a reason for staying at leeds, kill that and you kill some of the appeal of playing for us
