Of course it matters. Girls just learn to accept the fact that they're not as strong in come ways as boys. If they had to compete with boys in say middle school, at every turn, there wouldn't be as many girls in high school sports. And even less in college. Sports would be completely dominated by men.
The push of society to the left is going for ages. And left treat every of those issues as a "hill to die on". The category structure through which we understand the world is being openly attacked. This is not about a bunch of swimming broads getting cheated out of a fancy medal. Just as "gay marriage" wasn't last, or normalization of promiscuities, this isn't the last hill they're fighting on. They'll keep pushing until everyone is submitted to their way of thinking, since that's the only way they can function.
Let me put it this way. If man can be a woman, then it should be able to compete with woman. If men and women are equal, they should be sharing the same responsibilities and rights as men. But... if recognizing that women are not men, and not equal to men, than should they have the same responsibilities or rights as men? That is why they can't let this slip, and they're only mad now because it clearly and unambiguously proves that men aren't women. And if women aren't equal here, what else might they be "not equal" at? It destroys their whole narrative from the wage gap to voting rights, and they don't want you to talk about it?
Someone have mentioned before... I think it was
Cecilie1200 about funding women sports. That's exactly what is title 9 for. They’ve had to cut men’s programs and install made up activities so women can get a chance. Another rarely discussed topic how damaging sports can be to women’s bodies. People against men in dresses playing against women haven’t been paying attention and think the lunacy just started. I’m enjoying it because people are finally getting to see how crazy and protected female sports have been for years.
We warned about it, we were labeled as bigots and what not, because protesting against any leftist agenda is social suicide, at least outside the sports circles. When the problem gets too big, there will be too many affected women, and that will increase the odds of one of them coming out in protest, if that hasn't happened. Then others will follow suit. At first, it will be hidden away from the media and won't be reported much. But as it spreads, it will be too hard to contain the protests from the athletes. If enough of them take a knee as someone suggested, it can't be hidden from public much longer, that women refuses to compete against men, and eventually admit we're not equal.
