But, arbitrary how? Stupid how? You'll need to go a little further into this part.

I'm not quite sure what your question is. Do you mean, "why are gender roles considered arbitrary and stupid?"

I don't think you can say to truly have claim to be talking about feminine vs masculine roles in society if you can't even identify them and need to ask these questions.

Those were rhetorical questions. We all know what a "masculine" job is, and what a "feminine" job is.

That image macro made my brain hurt.

It's simple enough; traditional men's labour is capitalised, traditional women's labour isn't.

I don't think you understand how the world works. People make contracts with one another in business. People are rewarded for their offering provided for a business - skill, knowhow, work done, etc. Supply of labour, of the specific expertise, and demand, form what is compensated to this person for what they put in. You're comparing this to a woman who stays at home and performs homely maintenance duties as well as cooking and looking after children, for herself and her family, and then ignoring that all her expenses and more are paid for the man? Such strange folly this is.

Of course they're paid for by the man; in the traditional family unit where Dad-works-and-mum-cleans-and-raises-kids, the dad's labour is the only one that makes money. Of course the woman's expenses are traditionally paid for by the man; there's no other way to pay it. That's obviously not a good thing.

A man being employed is being a good dad and "providing for his family".

A woman being employed is often seen as neglectful, and "putting her job before her kids", despite the fact that men almost always hold similar roles and that's seen as normal.

If economically, it were just as important, then the pay would be the same, but it's not.

How profitable something is, is not the same as how important it is to society in general.

I think we might've been talking past each other or something, because far as I can see, I don't feel like I'm arguing for or against something, just stating facts...
