The Little League World Series is a complete novelty event that is barely serious at all - its just fun to see a bunch of little kids get the spotlight on TV. At the end of the day all of those kids go to school and live a normal life like any other kid their age. The "sell" of female professional athletics is that it is a professional endeavor no different from men's athletics. The women are professional athletes whose job is to excel in their given sport. It's a little harder to take that "sell" seriously when you realize that in virtually all of those sports, the best women on the planet would, and DO, get beaten badly by teenage BOYS. Not "men" as you put it, but BOYS. The US Women's NATIONAL soccer team (the best women's team on the planet) lost against the FC Dallas Under-15 boys team. Not the "Under-15 National Team", but a regional team of what? 9th graders? The same is true for the Canadian Women's National Hockey team who have played, and routinely lose against random squads of boys barely past puberty. So this isn't even a question of comparing a top female athlete to a top male athlete - it's literally a situation wherein you can say with confidence that there are hundreds of 15 year olds in America alone who are better soccer players than Alex Morgan - or whoever the best professional female American soccer player is.
This is what makes their ridiculous cries for "equal payment" even more ridiculous. Not only do their sports make next to no money, but the idea that they should be paid equivalent to their male counterparts is even harder to fathom when you consider that all of these women are at the equivalency of about a good high-school boy.
