Then it would be the womens 900m race instead.
Equality doesn’t mean we must do everything like men. Why is the mens version the bench mark that womens sport should be measured against?
Yes, women have the heptathlon and the men the decathlon, and that doesn't seem to be a problem for anybody. Plus, the main skill in those is in pushing your own body to the limits of what it can achieve rather than to use it to try to seriously injure somebody else's body.
As for the 'protecting reproductive' organs thing, women's reproductive system as a whole is higher up and covers a wider area than men's, which hangs down out of the way and is relatively easy to avoid hitting by accident.
Also, the glaring difference is that a man will never be pregnant, whereas a woman could quite conceivably (so to speak) be in the very early stages of what would be a wanted pregnancy without even knowing. In fact she may be further on in her pregnancy and fully aware of it, but nevertheless still decide that she wants to continue boxing - after all, men don't get told to stop when they're soon going to be parents. Pregnancy usually involves the tiny person inside doing the punching and kicking - not being the recipient of it.
I absolutely detest ALL boxing and I firmly reject the argument that 'all sports have an element of risk'. Of course, this is true, but in almost all sports, the risks can come into play by accident, when something goes wrong. With boxing, it's the express purpose of the sport to aim to cause somebody injury. We're so inured to the terminology, but take a moment to think about it: the target is to knock somebody out - ideally unconscious. That's oceans apart from running the fastest, jumping the highest or lifting the heaviest weight.
Would we be so blase about synchronised swimming if the 'most expert' routines were considered to be ones where one of the swimmers stands on top of the other one, who is lying on the bottom of the pool and struggling for breath? Would we see it as a true noble skill to cause somebody to nearly drown (or to be the one nearly drowning yourself), but just about manage to resurface in time to survive?
Would dressage be considered as harmless if routines regularly included choreographing the horses to throw the riders off and trample them? Or, to swap it around, if the horses had to escape somebody whacking them with an iron rod like a pinata? If that were considered THE very finest, professional demonstration of sporting prowess?
