Of course not. Humans (including men) show parental care to increase their young's fitness as well. Human males are not solely obsessed with the mechanics of reproduction (as many animals are). Instead, most men also want to pass something on to their children that will set them up for success, and if you look at it, throughout history, most men were striving for this and most social structures evolved to make this possible.
That being said, having kids brings so much perspective to a life already lived. You almost live a second (or third, forth, fifth, etc) life vicariously though them, so it's up there in "experiences to have".
And yes, in general there is almost nothing more important other than reproduction from the perspective of species. Nothing controversial about that either.
Nevertheless, that statement does not say that there is not a life for everyone. It merely states that there is an inner drive to have children, see them grow and ultimately take care of you and the world. And this inner drive exists despite many people trying to say otherwise.
I mean it might be cool to work for $BIGCORP and build your career. You get cool things like nice car, nice suit... But the $BIGCORP will not hold your hand when you are scared before surgery, it will not help you move something when you are old and most certainly will not wipe your butt when you are too old to get up on your own.
i have children because i love them and want to care for them. i would adopt children for the same reason. i felt no drive to have children be my own. i could not care less if it is me who reproduced instead of someone else.
of course if humanity as a whole were in danger because there are not enough kids then i would want to contribute that however i can. but even then that could mean helping someone take care of their kids so they can have more kids.
If you personally don't feel that drive, there is nothing inherently bad with you and you certainly can have full and happy life. Maybe even happier because you can separate your decision and weigh pros/cons of having kids wihtout emotional involvement. But you are still probably a statistical anomaly. :)
as for offending, i guess i am generally bothered when people make assumptions about other peoples motivations
Plus I'd say that to have kids (in a family sense) does not necessarily mean they have to be your biological kids as I think that the bonding/family aspect of it is much more important than simple reproduction. Atleast for the mental well being of a person that is.
