In an attempt to connect the chart with marriage equality, Heritage Foundation member Ryan T. Anderson says the following:
“[R]edefining marriage further distances marriage from the needs of children and denies the importance of mothers and fathers. Redefining marriage rejects as a matter of policy the ideal that children need a mother and a father,” explains Heritage’s Ryan T. Anderson. “Redefining marriage diminishes the social pressures for husbands to remain with their wives and children, and for men and women to marry before having children,” he continues.
In other words, according to the Heritage Foundation, marriage equality (notice how they attempt to change the term to “redefining marriage”) leads to more single-mother families mired in poverty.
Bear in mind that the Heritage Foundation offers no proof that marriage equality leads to single-mother families.
And that amazingly brazen leap of logic is why NOM, the Heritage Foundation, and those who support their endeavors against marriage equality are losing the fight.
