I get the sense that you've got a lot to say but, for some reason, aren't saying it. Instead just resort to "fluff", ignorant, wrong, uniformed, etc., etc.
My fluff comment on the USA being the tide to eventually float all boats is certainly supported by a 5 second Google search:
"USA was the first ever country to include more women than men in the Games of 2012 in London (269 women and 261 men). That has had a positive impact on their performance, as women won 58 medals and men 45, thus sending the USA to the first position. 4 years later, they followed the same pattern, sending to the Games 292 female athletes of a total of 555. This is the largest value of women participating for any nation in the history of the Olympic Games.
The recipe was successful once again: USA was the leader in the final table, totaling 121 medals. The biggest success achieved by the women of team USA, who won the majority of the medals. At the Rio Olympics, 61 of USA’s 121 medals were won by women, while men won 55 (5 medals were from mixed events). Furthermore, from the 61 female medals, 27 were gold.
Many countries soon started following the same pattern, understanding the importance of women’s participation. Australia, in the 2016 Olympics won 29 medals (41.5% was from female athletes) reaching the 10th position with 5 out of 8 gold medals won by female athletes."
So while other nations are following in the USA's women-in-sports strategy, they still have a ways to go. I mentioned Europe is there but if you're a country of 4 million it will be hard to compete with the USA's female industrial sports complex on a national team level. This speaks to the dearth of competition (beating Thailand 13 - 0 in a World Cup). It would be interesting to see how many soccer players the US has to pick from in club/NCAA leagues versus Europe and the rest of the World.
If you can't get over my "liberated" assertion, let me better define it for you; I gauge a country's level of liberation of its female population by how many sports opportunities they have (I know, I know, I'll save you the effort of typing "rudimentary" for a curt response). So Norway? Highly liberated. Saudi Arabia? Not so much. This might get you or me to amend my original assertion that the USA has more females in sport (re liberated) than the rest of the World combined.
