Had this very discussion this weekend with one of my friends as his brother in law is openly gay and in a civil union marriage.  His son is 6 years old and his fear is that his son's making connotations towards what mommy is doing and what daddy is doing and why uncle kenny is not doing the same.  He feels it is his responsibility to shelter his son from potential harm at home and school.  It comes down to chores and doing things with dad and mom.  The dad is an electrician by trade and mom is a high school teacher.  Now the mom is in an uncomfortable situation, as she feels that if she as an example makes dinner, then that is something that women does, whereas dad makes food by way of having a braai and grilling the meat on the braai.  Whereas uncle kenny, as a chef, does the cooking when he visits.  So she feels that because their son is still so young, he can't make the distinction between a job/hobby and things that men/women do.

Hope I make sense?
