It is a good question to ask if things are getting worse. I think social media makes it seem as if the whole world is polarised. Some of the stuff on Twitter about Hillsborough, Heysel, Megan, The Queen, etc etc is just pure poison. Perhaps these sort of people always existed but 30 years ago they would be the person you avoided in the pub because you knew someone would punch them at some stage of the night. What has happened to the centre ground?
Believe it or not there are plenty of decent Liverpool fans and I have met some of them. But these days the only voices you seem to hear are the total scumbags and I think it poisons all of us.
