Reading through OP, have been trying to get a relativism of your content with the threads subject but, I just don't nail it right. My views as to politics and sports brings me to a point of dishonest practices where some players could be favoured more than others as per figuring in a game, where referees seems to give the home base team a chance to lead, where players of clubs origin are rationed to have more playing time as opposed to others despite qualifications and fitness.
Although, in the context you've raised which I see to be more of societal ills, football as a sport and sports in general is one solution to them. It doenst matter that athletes are there to compete but, it showcases the talents in them races, generates income for a course, teach reasons to why what should be what and harmonises the people. Sports and football in particular is doing a lot to correcting certain societal ills and should be left that way.
