Is Heinlein's Future History Coming True?

In 2017, David Brin wrote an essay called Looking back at Heinlein's Future History - coming true before our eyes. I wrote a blog post about it then, and I'm posting about it again, because it's even more relevant now. 

Heinlein has fallen out of favour these days, and there are some valid reasons for that, but he was right about the threat of religious fundamentalism and its link to authoritarianism. This is from the afterword to his collected Future History stories. 

It is a truism that almost any sect, cult, or religion will legislate its creed into law if it acquires the political power to do so, and will follow it by suppressing opposition, subverting all education to seize early the minds of the young, and by killing, locking up, or driving underground all heretics. This is equally true whether the faith is Communism or Holy-Rollerism; indeed it is the bounden duty of the faithful to do so. The custodians of the True Faith cannot logically admit tolerance of heresy to be a virtue.

Nevertheless this business of legislating religious beliefs into law has never been more than sporadically successful in this country – Sunday closing laws here and there, birth control legislation in spots, the Prohibition experiment, temporary enclaves of theocracy such as Voliva’s Zion, Smith’s Nauvoo, and a few others. The country is split up into such a variety of faiths and sects that a degree of uneasy tolerance now exists from expedient compromise; the minorities constitute a majority of opposition against each other.

Could it be otherwise here? Could any one sect obtain a working majority at the polls and take over the country? Perhaps not – but a combination of a dynamic evangelist, television, enough money, and modern techniques of advertising and propaganda might make Billy Sunday’s efforts look like a corner store compared to Sears Roebuck. 

Throw in a Depression for good measure, promise a material heaven here on earth, add a dash of anti-Semitism, anti-Catholicism, anti-Negrosim, and a good large dose of anti-“furriners” in general and anti-intellectuals here at home, and the result might be something quite frightening – particularly when one recalls that our voting system is such that a minority distributed as pluralities in enough states can constitute a working majority in Washington."

He was right to be worried about it when he wrote this in the early 1950s, and we should be worried about it now.
