I'm in the US and not a sports fan and I regularly find myself in groups where the topic of conversation is sports. It's a little uncomfortable for me because it's assumed that all men are sports fans in my city (Boston). My girlfriend recently cultivated an interest in sports so that she could fit in better with her predominately male colleagues. It seems to have worked for her. I can't tell for sure how much she actually enjoys it vs. how much she enjoys watching some play that she knows she'll will be a topic of conversation at work.
