"That's the issue right there"
I ... don't think you understood my response. Three months of it can only be taken by the father. The "split between either parent" has limits.
What's wrong with the non-mandatory Swedish system? It's most assuredly called "parental leave here", and isn't a "woman's issue" but a feminist issue. As a male feminist, I agree with that.
Edit regarding "it is you who is not getting me".
You are right. But I fail to understand why I should get you as you haven't made any statement about what "mandatory" means. Do you mean one week of mandatory leave, or one month, or one year? Will it be paid leave, and structured similar to what it is in Sweden (percentage of salary, with cap)? What is the penalty for not complying? If I am an unpaid board member of a Fortune 100, am I prohibited from attending meetings? What about going to shareholder meetings? Going to professional society meetings?
You complain that these questions are "trying to take the idea down based on implementation details", but they are not. They are aspects of trying to understand what you mean by mandatory parental leave, and do a cost/benefit analysis
If Sweden were to require on week of mandatory parental leave, for each parent, how would that improve things?
