"I think you are right, it's good to have agreed gender roles. There is crossover in any good marriage and you can find exceptions where say a masculine husband likes his wife being a mechanic. However for the sake of society it's a bad thing to for that to be common. If women do 'male' jobs it undermines the need for men. People may say it doesn't, that men will always be needed, but men will see women doing their kind of work and it will undermine their sense of unique male purpose. For boys learning what a male is, it's demoralizing, distracting or will push them to look elsewhere for meaning. They learn early on that masculinity is labelled toxic and at the same time female aggression towards men is viewed more positively now than in the past. We are in a terrible place in the West where people are not marrying and having families to the extent we need them to. Men need to take the heavy load in the workplace and women need to be homemakers. It just is what it is. Exceptions that do not look like failures (yet) do not make that untrue."
