Agree absolutely! It is truly amazing that in 2017 the Cath- church would sponsor a conference on the family with no more than 10% being married people. Ridiculous! Outrageous!
Reminds me of the Birth Control synod sponsored by Pope Paul VI back in 1968 --NO MARRIED COUPLES invited in the first session! Then, when someone noticed how odd it was to have a conference on birth control without any married couples being present, 3 married couples were invited to the next sesdion - 1 from U.S., one from South erica and one from Europe. Unfortunately, their presence didn't make any difference -- ths birtg control doctrine remained unchanged.
And now, almost 50 years later, another conference on the family -- and still no families (with children!) invited. How pointless! 
New motto: 'No discustions about us wihout us!'
