Gender equality is still possible, just perhaps not the equality that you're thinking of. Equal opportunities should be present for all genders. All genders should be getting equal pay for the same amount of effort put into work. All of those don't need to take into account any gender differences at all.
I believe that pretending we're all the same and we all function the same way is just as misguided as regarding one group as inferior to the other. I could equate it, for instance, to being black-skinned or white-skinned. There may be minute genetic differences, but overall when afforded the same opportunities black people are able to acquire the same amount of education and be as productive in society as white people. That being said, it's plainly obvious neither of them are the same, and that there, to some degree, will always be a separation of culture. I believe that embracing the diversity of people is the right way to go rather than trying to erase it.
Saying that one gender is weaker than the other, or that men are less emotional, or something like that, is not embracing our real differences because those aren't existing differences in the first place; those were made up by falsified stereotypes and gender roles that don't actually apply. Unfortunately, these negative gender roles that place one gender over the other are the kind that are harmful, and lead men to be more aggressive as they're repeatedly discouraged from expressing their emotions, and force women to become self-fulfilled prophecies by not bothering to reach their potential because they won't be "as good as" a man. Saying something as innocuous as girls gravitate more toward feminine things naturally, though, is not a harmful difference to note.
Think of it this way: gender roles will stop having a negative impact once we stop seeing feminine and masculine things as one above the other, and rather as two sides of the same coin that allow for possible interlap between the two.
Of course, what gender you choose to present yourself as, and what interests you have classified as masculine or feminine, does not discredit you as one gender or the other, or something in between. Gender has much more to do about whether or not your body is in line with the map that your mind has for it, as well as other additional factors that I won't try to describe here as even I don't fully understand them yet. Either way, your interest in feminine or masculine things does not determine your sexual orientation or your gender; it's determined by something else hardwired within your brain, which has very little to do with gender constructs at all.
The point is that you were saying that it was 100% disproven, which the article itself is stating that it hasn't been. The possibility is still there, and unfortunately, given the history with women's treatment within the workplace, it's also still likely.
I am making no attempt to cover up the mention of men being raped in those, as I have made no claim that they aren't being raped at all. In fact, the statistics in the sites that I gave you say it's over 10% of victims, which is quite a lot considering how many rape victims there are in those statistics. That being said, it doesn't discredit the fact that more of them are women than men. Of course, it's very possible that these statistics are slightly inaccurate if only because the likelihood of women reporting their being raped is greater than the likelihood of men doing so due to the stigma that men can't be raped, a stigma that I believe should be abolished and we should be long past because of, as you said, us being in the 21st century.
I find it quite troublesome that sexual assault/rape is a problem at all, and it's still a very high ranking crime, and I think that statistics like these give more than enough reason to be at least a little cautious.
