I mean...there are a lot people on this forum who follow both genders and find equal interest (or at least enough interest) in both sports. Plus, women sports have been putting up great broadcast numbers in the United States, especially when given more optimal broadcast slots.
I don't think equally, or better phrased "equity," means we need to ignore biological difference necessarily. You can have discus for both genders and have a slight weight difference. However, if a majority of female athletes wanted the weights equalized, then I don't see a problem really.
Women also constitute a non-insignificant proportion of the global population. As someone with a degree in public relations, I'd argue the available research doesn't really support excluding large segments of your potential audience. Generally, not a great idea commercially or socially (at least in most circumstances).
I also don't think it's crazy to request equally pay (or earning potential, or business rights, etc.) when doing (essentially) the same the job. Yes, I understand the men's leagues rake in a lot more money, but that's also related to have less historical barriers to practice sport, getting more broadcast time (and better time slots), and more media exposure.
There are a lot of male athletes who complain about their pay, but still do some pretty remarkable things in sport. I think the last part of that thought is pretty moot.
I mean...again...I think there may be some policy related reasons for that.
I think there are also sports many American (or Japanese, or Ghanan, or Indian, etc.) viewers feel the same way about, but the beauty of the Olympics is the diversity of what's offered (at least in my opinion).
Skateboarding might not make the Olympics "more relevant," but I think same could probably be applied conversely on that point (and if people have a problem with athletes being too young, that can be tweaked of course).
