We've had some scum fans in the past and still do, I wouldn't deny that we had a vocal racist contingent and it is deeply saddening. I would point that Everton, although having massive racism problems, were not alone. I'd say Everton-Chelsea and Leeds were all similar in their race issues, I remember people actively zieg heiling at Elland Road and their fans still have large connections with the BNP/etc.
It has been pushed out now, of course there are still some idiots about but we are starting to see more ethnic minorities come to Goodison. A good mate of mine is black and says he hasn't experienced racism but his dad supported Liverpool because he thought he wouldn't be abused.
The UK, and Liverpool, has come a lot further over the past 20, even 10 years and racism just isn't acceptable anymore, when back in those days it was. I'm someone who misses the old atmosphere but you can see that one of the main benefits of the new kind of crowds it the abolishment of racism in football grounds.
