Each of separate points are valid there is no debating that. That they did try greedily destroy English football with the failed attempt of the super League, they did cause the banning of multiple teams a chance of being in Europe due to Heysal, they did support Suarez when he racially abused Evra.
But I don't know how chanting that song will solve or cause any positive change. It is simply a chant that you and other fans believe is a cheap shot at Liverpool fans, because you know it causes upset and will trigger them because they immediately associate it with Hillsborough.
The thing is the super league will happen eventually and the fact people only objected because it was the top 6. But if they extended it to ten or twelve teams I guarantee fans will change their tune. Which regardless the amount of teams chosen it would destroy the English football pyramid.
