There are probably 300 countries with pro sports leagues.Australians are so weird when it comes to their footy. Is there another country that is divided as us when it comes to a national sport? Imagine if half of the USA hated the NBA.
Your only comparison is the NBA. One league in one country....
90% of Americans could not give 2 fu**s about the NBA.
Nothing weird about our country.
I will say. Per capita we have a lot of pro football codes.
