"Family is composed of a mother and a father, and usually but not necessarily, children..."

...is Ken Epp's (Edmonton--Sherwood Park) argument. A mother and a father, but not necessarily children? Doesn't "mother and father" sort of necessarily imply children? This gets to the core of these ridiculous arguments about children I've been hearing all night. There are many heterosexual couples who aren't mothers and fathers. Children are not the reason men and women get together; sex is. Children are just a byproduct of that, and you don't have to be married to have children.
