No. I believe women, girls actually, are separated from their peers at an age where crucial development happens. Thereby not developing along side the best of the best in their age groups. Are there women that could play in the NHL and look no worse than Austin Czarnik? Absolutely. Is it worth the (social) media shit storm? Not so much. Would there be more if youth sports weren't segregated? Yes. Is it 50/50? Absolutely not. But it's also not 100/0...
Again, look at American men's soccer. Are American men incapable, physically, of competing at the top end? Or were they simply not developed properly?
