You really need to pull yourself out of this prehistoric mode of thinking.
Let me be clear. Gender roles are not "natural" at all. They are a societal construct created by people for a number of reasons. Sometimes these reasons were that it was vital for the survival of society. In other cases it was people acting in their own self interest. What I can say with utter conviction is that there is absolutely no necessity or excuse to persist with gender roles of the past in modern society, especially given how they continue to oppress and disadvantage women
You like to argue that it is "dangerous" to go against the so called "natural" order and yet you fail to understand that we have been doing this for millennia, and that the status quo which you're seeking to protect was the result of exactly this.
No. The problem is that people like you don't understand that the things we prefer based on gender are determined by society and what we're taught to prefer. In short, we're indoctrinated into it from the day we're born, and once we're part of the system, we tend to act to perpetuate that system, especially if we perceive that we benefit from said system.
Look at a country like Saudi Arabia. Most westerners are appalled at the way they clearly discriminate against women. Yet if you speak to most Saudi women about their situation, they will tell you it is the natural order. Furthermore the majority of women in that society perpetuate the system and pass it on to their daughters. The irony of course is that those same westerners who are quick to point fingers at the Saudis fail to see that we're not exactly perfect ourselves. We suffer from exactly the same inability to recognise the flaws of the system we're stuck in and continue to perpetuate.
Equality hasn't been achieved, but we are certainly closer to it than ever before. Many "privileges" that girls and women enjoy today were not allowed even a few hundred years ago. But yeah, I guess that was all "negative change"
But yeah I get it. If you happen to be in a position of privilege in an unequal society, of course the idea of change will be threatening. And of course it's in your own self interest to resist such change. But that doesn't make it right. It just makes you a selfish douche - even if you can't see it.
