Women's sport is chronically underfunded, under supported, and under advertised. This leads to a lower quality of junior programmes. Which leads to a lesser quality of play/skill, which leads to lesser interest which leads to... Being chronically underfunded. Return to start.
The (admittedly two week old comment) was not as sexist as one might well think. There is indeed a truism at play, that there is lesser interest in women's sport. However it is sexism that makes it so. Women are not inherently worse athletes, despite what your overly simplistic biology or health classes may have taught you. The average woman has different strengths (endurance, flexibility, agility) than the average man. But no such person, average woman or average man exists.
I'm a woman and I don't think an observation that women's sport is ignored is sexist. I think the reasons women's sport is ignored is due to a sexist feedback loop.
