We had a local black lad from toxteth playing for us in the 70's and Howie never faced any racist **** so what's your point, you're a petty prick to not hold your hand up and admit Chelsea fans treatment of Cannoville was totally abhorrent, and using other players as an excuse to make the lads life a living hell even though he played for the club you support shows the Chelsea support of those days to be top of the league when it came to racism.
Unfortunately they went from racism to combination of racism and fascism in later years, not something that can easily be swept away so just accept it and move on.
