I doubt most of society understands it well which leads to people taking extreme takes. Traditional gender rolls exist for good reason and aren't necessarily bad since the majority will follow them happily but there's no reason why individuals should be forced to follow them should they wish otherwise. Likewise there are cases where biology alone can cause bad outcomes for people and in such cases messing with it isn't necessarily wrong, but it's not something you want to mess with haphazardly without fully understanding the risks and trade offs. Honestly I think messing with social norms is similar. I think the wisdom of Ecclesiastes often reigns true from a study of history. There is nothing new under the sun. While we shouldn't blindly hold to traditions if we find new better ways of doing things, the argument that traditions are bad because they are old fashioned isn't a good one to me. These traditions exist for a reason, maybe that reason is a bad one and we should change it, but unless we actually understand the reason why beyond "it's old fashioned" I think we risk causing problems we can't foresee, perhaps problems that people in the past solved with such traditions.
