if it’s the majority, perhaps football itself should be outlawed?
But it isn't the majority. It's nowhere near even a significant amount. Even if a hundred people were involved in racist incidents at football matches every week (which they are not) that would represent a little over 0.01% of the total attendance at the four English divisions. To suggest that the remainder must accept "collective responsibility" for those miscreants is ludicrous. So it is with allegations of racism as a result of Brexit. It was said that those who voted to leave must accept collective responsibility for making open racism acceptable. To suggest that 17m people must be collectively responsible for making it so is just about as stupid as saying all football fans are responsible for the very few racist incidents that occur at matches. More than that, it's insulting to those 17m people whose only crime was to vote in a referendum in a way that some other people did not like.
There may or may not have been an increase in racist incidents since the referendum and/or the General Election, I haven't looked at the figures. But racism isn't acceptable, open or otherwise, and even if offences have increased I don't see any widespread evidence that its acceptability has changed significantly. The only alternative I can see to not ending up with results in an election or referendum that some people dislike is not to hold them at all.
