I've been plenty of times. That's why I have the issue. I think most of it comes down to the tactics used by the Rugby coach and the rest is just a secondary hatred that has developed.
Speaking of Millwall when I went to see them play Leeds at Elland Road they only brought 54 fans and as far as I know only one was arrested. The trouble the police put them through just to go to away games has put a lot of them off I think.
