Most of prejudices against the female gender come from the previous generations, especially in several cultures. Well it doesn't mean the children have to follow them, and while we hear a lot about feminism, outrages etc, I believe we're heading towards gender equality.
Sometimes it's even a bit exagerrated, as belonging to the female gender can be an advantage in contests.
In highschool, there is an engineer class contest every year in Paris, where people in Terminale (the baccalauréat year) can participate. The first and second places were the only groups full of girls, and while the first was extremely good, the second could be outclassed by the 3th, 4th, 5th places full of boys (talking objectively, i didn't compete in that event).
Then, last year, a tough year with plenty of oral mock exams, everyone (both genders) believed that girls had an easier time in oral exams, and by that they were talking about the mark and the teachers (both genders too!) being more helpful.
So yeah, I'm very positive about this subject in developed countries, where every culture is represented, shared, and talked about. We as humans evolve, we change our weaknesses. Gender inequality is such a weakness, and we overcame more than that, dunno why we should stop there. =p
However. if we are talking about countries in which there is only a dominant culture, then that's different. The parents teach their children what they think, and the offspring won't change their mind because they don't see anything different around them. If everyone tell you "yo Soysauce is a real Kirby" and seem to live conveniently with that (they believe, or they accept), why would you think otherwise? If you do, it takes a lots of effort and enough power/reasoning to influence people.
And the main problem today, is that outrages about this or that happen in our own countries, while we should look outside and see what the real deal is. Solve this, and everything's good everywhere. =p
Tldr; Soysauce is still a freaking Kirby and we should talk about sth else. =D
