Why are "women" treated differently than men in gymnastics?

Watching the women’s all-around tonight, I noticed that in the uneven bars, when the women do a release move (let go of the bar), they all have a spotter in case they fall. In contrast, when the men do similar (even higher) moves on the high bar, there is no spotter. So, women need to be “protected” in gymnastics, but men don’t? What gives?
And if anyone wonders why “women” is in quotes, I will say that I don’t consider 14–15 year old girls as women.
