Avioliitto on naisen ja miehen välinen julkinen liitto

"Conclusion
"The articles by Marks and Regnerus have completely changed the playing field for debates about homosexual parents, "gay families," and same-sex "marriage." The myths that children of homosexual parents are "no different" from other children and suffer "no harm" from being raised by homosexual parents have been shattered forever."

The Family Research Council (FRC) is an American conservative Christian group and lobbying organization formed in the United States in 1981 by James Dobson. The FRC promotes what it considers to be traditional family values, by advocating and lobbying for socially conservative policies. In 2010, the Southern Poverty Law Center classified the FRC as an anti-gay hate group, a designation which generated controversy.
