Nah it goes back much further than the 80’s, when we’re on the topic of the age of American Christian Nationalism I like to break out the only Barry Goldwater quotes I know, the first of which was said in the 60’s:

Mark my word, if and when these preachers get control of the [Republican] party, and they’re sure trying to do so, it’s going to be a terrible damn problem. Frankly, these people frighten me. Politics and governing demand compromise. But these Christians believe they are acting in the name of God, so they can’t and won’t compromise. I know, I’ve tried to deal with them.

Another banger:

I must make it clear that I don’t condemn these groups for what they believe. I happen to share many of the values emphasized by these organizations. I’m frankly sick and tired of the political preachers across this country telling me as a citizen that if I want to be a moral person, I must believe in “A,” “B,” “C” and “D.” Just who do they think they are? And from where do they presume to claim the right to dictate their moral beliefs to me? And I am even more angry as a legislator who must endure the threats of every religious group who thinks it has some God-granted right to control my vote on every roll call in the Senate. I am warning them today: I will fight them every step of the way if they try to dictate their moral convictions to all Americans in the name of “conservatism.” … This unrelenting obsession with a particular goal destroys the perspective of many decent people. They have become easy prey to manipulation and misjudgment.

Yet another prophetic quote:

There is no position on which people are so immovable as their religious beliefs. There is no more powerful ally one can claim in a debate than Jesus Christ, or God, or Allah, or whatever one calls this supreme being. But like any powerful weapon, the use of God’s name on one’s behalf should be used sparingly. The religious factions that are growing throughout our land are not using their religious clout with wisdom. They are trying to force government leaders into following their position 100 percent. If you disagree with these religious groups on a particular moral issue, they complain, they threaten you with a loss of money or votes or both.

Another one:

The specter of single-issue religious groups is growing over our land. … One of the great strengths of our political system always has been our tendency to keep religious issues in the background. By maintaining the separation of church and state, the United States has avoided the intolerance which has so divided the rest of the world with religious wars.

Yet another accurate one:

Those who seek absolute power, even though they seek it to do what they regard as good, are simply demanding the right to enforce their own version of heaven on earth. And let me remind you, they are the very ones who always create the most hellish tyrannies. Absolute power does corrupt, and those who seek it must be suspect and must be opposed. Their mistaken course stems from false notions of equality, ladies and gentlemen. Equality, rightly understood, as our founding fathers understood it, leads to liberty and to the emancipation of creative differences. Wrongly understood, as it has been so tragically in our time, it leads first to conformity and then to despotism.

This lot are indubitably amongst those actively calling the teachings of Jesus “weak” so yeah, definitely not Christians.

They are Mammonites.

Tell me what idea they express that does not align with the Christ fable.
