Should a man be force/compelled to 'marry' a woman that he's 'accidentally' made pregnant ?

I don't think so. Since when has marriage had anything to do with being a parent? You can be a fantastic relationship partner but a completely shit parent, or a fantastic parent but completely shit at relationships.

I don't buy that there's any linking between 'christian values' and being married. Or being a parent.

But others may beg to differ.
