I would rather have no father than a father who wouldnt want me. Therefore I fail to see the relevance of the whole 'own up to your responsibilities' talk.
If you generate kids as a man I believe you should take responsibility to the best of your ability. That means paying alimony and arranging either a nanny or an au pair to help the mother out. But why be there for the children if you absolutely do not want to be there? You cannot fake 'love' or 'being happy' around kids when you really aren't. Imo that's much more immoral behaviour than simply not being there. I do believe a man should pay up in the form of alimony naturally.
Ofcourse I can understand that there are many people here who would love to be a father and/ or sympathize with single mothers out there but that doesn't really counter my initial statement: "I would rather have no father than a father who clearly doesn't want/love me".
