Of course the same-sex marriage referendum is about children

Voters should acquaint themselves with the relevant constitutional article (Art.41). This provides context to the proposition that “marriage can take place between any two people without distinction as to sex.”
Everything that goes before this proposed addendum to article 41 is about family and the unique value of marriage, because it is on marriage that “ the family is founded.” If the referendum passes, that is a constitutional acknowledgement of the equality of heterosexual couples, who can found a family, and homosexual couples, who clearly cannot.
