But who says the definition is to attach mothers and fathers to children and to each other? Same-sex couples can adopt children and opposite-sex couples can not have children. And claiming that homosexuals have equal rights to heterosexuals because they can also marry people of the opposite sex is just. Not a good argument. Heterosexuals get to marry the people they want
to marry, homosexuals don't (/didn't).
