The clear exaggeration of this person conflating the backlash against trans issues in primary school with life becoming intolerable not withstanding. There is a small but persistently significant minority of Christians who essentially could be described as promoting a theocratic form of nationalism. Fascism isn't an accurate discriptive though.

Essentially these people believe that it is the duty of christians to run the government in a way that god will favor less god himself rain down divine punishments. They are essentially progressives in many ways save their opinions on abortion and gay marriage. See it as their divine charge to legislate morality.

It's nothing new in the American political landscape has existed since the puritans at least. They basically started a state where the church held a huge amount of political power and religious dissidents were shunned and banished from the territory. It's how Rhode Island territory got started after they banished Roger Williams for wanting to be tolerant to the Jews and other religious groups that didn't want to join the puritans.

These days the hardline political christians, some call them dominionists but even that exaggerates the level of organization and solidarity there is within their ranks. They largely hold only the the following in common, that America is a Christian nation and our government should reflect that, and that America needs to pursue good moral policies. They cannot however come to wide agreements on what being a Christian nation means, or what those good moral policies should be. So whenever they do gain some power they'll usually see a splintering of their base which allows for their opposition to make back their gains.

If we actually saw them gain wide power the only real issues they'd come to any agreement on would be repealing gay marriage and restricting elective abortions. They'd be unable to gain wide agreements further than that as exactly what restrictions on abortion should be would fall to debate and cripple their ability to get things done, and there would be endless bickerings between the progressive moralist authoritatian wings that see it as their charge to legislate vice from the world as the push for restrictions and bans on such things as gambling, guns, alcohol, tobacco, violent movies and TV and the like, and the more libertarian-esque leave us alone to do what we wish freedom focused constitutionalist types that would be pushing for smaller government and less power to enforce the kind of moralistic legislation the other wings want.

What people on the left fail to realize is there is no solidarity between the different groups of Christians beyond this vague idea of needing to fight against the liberal democrats. Christian groups will split their churches over even the most minor of doctrinal disagreements. They're threat to American democracy is hugely overstated, wherein lies the real danger of fascism. As the left continues to demonize their opposition and paint them as dangerous threats to society they only serve to further the attitudes that will lead to people thinking increasingly authoritarian and political restrictions on freedom of expression are necessary to stop this fictional existential threat to our society.

It's important to recognize the radical Christian Authoritatian wing of the republican party as something that's real, but we shouldn't overstate their importance or power as anything more as what it is, a small but rabid group that have a significant impact on republican fundraising and are easily influenced with the right kind of messaging. But hold little real political power and never will due to their inability to compromise or form coalitions.

As they say a fool and their money are soon parted. If you know the dance and song they like they'll throw money at you if you sing it.
