It seems the attitude is that only women desire abortion or that it's solely a woman's issue, choice, "sin". And that is certainly not the case whatsoever.

In today's society, it is. The woman is the ultimate decision maker on this issue. It shouldn't be that way, but that's how it is right now. Whether or not a man is pro-abortion or pressures her into getting one, ultimately it won't happen unless she goes to the abortion clinic and gets it herself. If the man tried to do it at home or something, he'd be in prison or get the electric chair.

It's as important to fix men's mentality about fatherhood and stop glorifying the eternal Peter Pan syndrome of not wanting a family or responsibility or to grow up

The men who think that way think like their mothers. They hate and distrust their mothers and due to that, they take on their feminine mindset. (and remain boys) Unfortunately people have turned away from God and the traditional ways.

So what ends up happening is men get involved with women only for sex, and treat them as their gods, and in some cases get married and/or have children. They don't realize it, but they've married their mother and don't know how to deal with her. That's what leads to what many people think of as the father "abandoning the children".

It's usually not that at all, it's just that the mother drives him crazy and he doesn't know how to handle her, so he leaves. I agree that men are more to blame. It was men who allowed feminism and all this nonsense to come into being in the first place.
