Yes. I do. Liverpool is a fairly working-class port city in Northern England; most people from Liverpool are descended from Irish immigrants who poured into the city during the famine and after. The constant stream of Irish immigrants since the 1850s has given the city a very distinctive accent and a predominantly catholic culture. Consequently, a lot of scousers (people from Liverpool) do not even consider themselves English and actually hate England/English people/English culture. 'We are scouse, not English' is a common chant in Liverpool. Liverpool fans recently booed the English national anthem at a match. Support for the IRA has been high in the past in parts of Liverpool and they never vote conservative.
In 1989, the Hillsborough disaster happened and tory/Thatcher supporting Sun newspaper blamed the Liverpool fans and not the police. Scousers mass boycotted the Sun; they hate the conservative party and Thatcher for her 'managed decline' and hard neo-liberal attitude to economics which fucked the North in general.
Hence, a lot of 'soyboys'/ men with left-wing views who want to get into football, but don't like the general working-class patriotic and reactionary view of a lot of English football fans, decide to support Liverpool despite never having lived there. After the whole Hillsborough shit with the police and the Thatcher government went down in 1989 tonnes of young people with left-wing/socialist views decided they were Liverpool fans.
