Current situation:

A man and a woman have sex.
She gets impregnated.
He accepts, or not, ‘the responsibility’ and, sometimes, helps with raising the child.

Isn’t it high time to change our attitude about all this?

How about:

A man and a woman have sex.
She gets impregnated and decides to keep the baby.
She acknowledges, or not, his contribution and allows him to take part in raising the child.
