What these people really mean is white nationalism.
the people espousing 'Christian nationalism actually doean white nationalism but they think they can trick people by pretending that they only care about christianity...since being white is supposed to be far too taboo.
But this isn't tricking anyone and it causis the message to be incoherent. White nationalist At least DO have a coherent message that Is internally consistent...and that is the only thing they have on their side. And the only reason their interests are taboo is because the media and education system have made it thus and brainwashed people. 100 years ago it was a totally ordinary point of view that seemed quite sensible to almost everyone. When the 1965 immigration act was passed, jfk had to lie and say it would not alter the demographics of the usa (if that were remotely true, then there would be no reason for the immigration laws to change in the first place)
back in the 1600s, the chief Justice John holt was asked whether black people were protectprotected magna cThailand thus could not be slaves. He said no, because they are not Christian and all rights come from God. But when black people did convert they did not get freedom...so it is quite obvious he spoke in bad faith and religion was simply being used as a proxy for race. The hilarious truth today is that immigrants from the 3rd world are far more Christian than white people, while the Christian nationalists want to shut down immigration. It is a silly contradiction.
Indeed...i would say that if jesus meant anything at all, it was that anyone would become christian...whereas the old testament taught that only jews can worship the god of the jews. Christianity is fundamentally universalist and race blind...although ironically it is ALSO very anti semitic.
