I was in a bar with a friend last night and the England match was on and there were a lot of people there watching and cheering England on. Similarly when the scores came up to show Scotland, Wales, NI and ROI losing there were also massive cheers. My friend then started arguing that nationalism is linked with extreme ideologies and is a deeply harmful and corrosive influence on society and that it is going to lead to the disintegration of the UK. AIBU to think that support your nations football team against others as well as relishing seeing others lose is pretty harmless and presents no threat to society.
