Former president Ronald Reagan's son Michael Reagan published an article on Tuesday calling for churches and politicians to take notice of the moral consequences of gay marriage, stating that it would lead to "polygamy, bestiality and perhaps even murder."
Reagan, who works as a political consultant, said Republicans are too caught up in the next presidential election to fight against gay marriage.
He also criticized church leaders for failing to recognize the consequences of its legalization.
"Where's the moral outrage?" he asked. "Why aren't thousands of our pastors, priests and rabbis shouting from their pulpits? Why aren't they leading their congregations through the streets in mass protest?"
He argued that its legalization will "inevitably lead to teaching our public school kids that gay marriage is a perfectly fine alternative and no different than traditional marriage."
The marriage of two same-sex people, in Reagan's opinion, might even lead to the questioning of any morally-based law.
"There is also a very slippery slope leading to other alternative relationships and the unconstitutionality of any law based on morality," he said. "Think about polygamy, bestiality, and perhaps even murder."
The churches must get "engaged and start fighting for America," he wrote, and should stop "wimping out."
Reagan believes religion is capable of preventing it from being legalized, and that despite mainstream media being supporters of its legalization, churches made up of millions of members will hear their voices heard "and even the Supreme Court will feel the political wind."
