"Proof" of the harm of marriage equality

From this article:

Also during the panel discussion, Tom Minnery, senior president of government and public policy for CitizenLink, offered statistics that he said demonstrate countries with same-sex marriage are worse off than places that deny marriage rights to gay couples. LGBT advocates have long disputed the statistical accuracy of Minnery’s work.

Minnery said responders to a survey were asked whether married people were happier in countries with varying levels of relationship recognition for same-sex couples.

According to Minnery, in countries with same-sex marriage, 21 percent of responders said married people were happier; in countries with civil unions; 36 percent say married people are happier; in countries with only regional recognition, 42 percent of people said married people were happier; and in countries with no same-sex marriage, the respect for marriage “goes high.”

For another question on whether children need both a mother and a father to be happy, Minnery said 76 percent of responders said “yes” in countries with same-sex marriage; 80 percent of responders said “yes” in nations with regional recognition; and 93.8 percent of responders said “yes” in countries with no same-sex marriage.

In short, in countries where people are more likely to agree with Tom Minnery, people are more likely to agree with Tom Minnery. If that's the argument, he should just give up and learn to cope with all of the nothing that actually will happen.
