You are better off being a genetic full stop,
Being a man, I can think of many reasons for a couple not to have children that don't revolve around careers.
-Reproductive problems (his or hers)
-Genetic predisposition to medical conditions being passed to the offspring
-Care for the environment (the earth can't continue absorbing so many humans, so I/We won't contribute to the problem...)
-Concern about the society we live in (why would we bring children into such a messed up world...)
-Knowing you could never financially bring up a child in a manner in which the child deserves (financial....)
-Having a life threatening illness that you know would cut your life short
-Mother's history of medical reasons that would be a threat to the baby / mother
Mentioning our children is fecking personal.You back off.
Seems to me you are being the heavy. No need for that.
