I work 5 days a week in a job where I have to be polite and calm often in the face of very aggressive situations. On a Saturday I can shout at players , opponents and officials in a manner that would get me sacked at work. It’s therapy for many. I never racially abuse people, I am not sectarian and not homophobic I just like thousands of others enjoy a good rant at the football . I also love cheering ( not this season obviously)
