That's exactly my point, I chose to support Leicester. You're saying people shouldn't choose a national team to follow.
You've also crossed two points, not sure if it's on purpose. I don't get national chest-thumping, St George's waving patriotism, because I don't get why I should be proud to be English. It seems a bizarre concept to me. I don't care about the national football team because I have no draw to them. They aren't a team I've chosen to follow, but would be doing so because it's expected as an Englishman. It's not a difficult concept.
