Christian conservative James Dobson ranted against President Barack Obama's transgender bathroom policy in an op-ed published this week.

Dobson, the founder of Focus on the Family, called on parents to “shield” their children “from gender feminism and from those who would confuse their sexuality.”

The policy, issued jointly by the Education and Justice departments, advises schools that receive federal funds to allow transgender students to use the bathroom of their choice.

Dobson said that the directive made him “sick” and that Obama was acting like a king.

“Did it upset you when the president of the United States ordered every public school in America to open all its bathroom facilities including those that are in use by a member of the opposite sex?” Dobson wrote. “The president’s order made me furious, and then sick to my stomach. How dare this man do something so audacious and unthinkable! His letter from the White House carried an implied threat to withhold federal money from local schools, which rocked the halls of public education. Who is this politician that is spending your hard-earned tax dollars to manipulate school officials, anyway? Who is it that is warping our children? It is Barack Obama, one of the worst presidents in American history, and it is time we stood up and said so!”

“Obama, acting like a king, is wielding dictatorial powers never envisioned in the law. He is determined to change the way males and females relate to one another, and worse, how children perceive themselves.”

“How dare he assault centuries of modesty and moral beliefs! By what authority does he tell parents and school officials what to teach children under their care? Christian parents, does this outrageous order violate something deep within your sense of propriety? The president has already maneuvered the courts to undermine a 5,000-year-old definition of marriage, after experiencing his infamous epiphany. Now he is determined to change Western civilization forever. He becomes more reckless and defiant as his second term comes to an end. Never has an American president been so absorbed with the use and abuse of power, and unfortunately, he still has seven months to go. What is next?”

He concluded: “Clearly, there are serious implications here for mothers and fathers. I urge you to protect your boys and girls from those who are espousing these views. Shield them from gender feminism and from those who would confuse their sexuality. They will be under increasing political pressure in years to come.”
