You have great points especially this:

If we're not careful, sometimes in a bid to radically eliminate something, we only create the same thing or something worse in another form.

I say we've reached a truly equal society free of gender biases when the time comes that job applicants are measured based on skills alone, and companies would not need to worry about lawsuits on equal opportunity Coal mining for example, should women want a job in this area then they'd need to have the strength necessary for the job.

In the same manner that should a woman apply for a top-level executive position, she and the rest of the candidates will be assessed purely on skills. At this time, it still does exist that most institution has a preference for male leaders.

There wouldn't be any need for gender roles in the society as well. A man or a woman can take on the provider or the nurturing role without any stigma.

And maybe when that time comes, we no longer have a need for the term feminism, and replace it with humanism perhaps?

Sidenote: the maternity leave grant is more for medical purposes at the minimum, and for the child-rearing purpose for the extended one as the mother can provide milk. But I do get what you were trying to say here :)
