All increases in immorality work toward the breakdown of the family and nation, on the physical, financial and spiritual level, while obedience to God promotes its well-being. See http://peacebyjesus.witnesstoday.org/RevealingStatistics.html for temporal costs of war against God.
Are gays are more likely to contribute to this breakdown than non-gays?
Do we have some empirical evidence on that or is that just your opinion?
