Christianity for defense against islam

It's understandable that Christians lie to push their type of stupidity, claiming that it might somehow help resistance against Islam.
But now even atheist Youtubers have bought into that insanity.
I think some of it is to pander for donations from Christians.
Nonetheless, I'd like to refute this assertion here.

Conservatives instinctively value tradition:

And they recognize Christianity as tradition, so they have an instinctive bias in favor of it. Where progressives oppose their own traditions, so they have an instinctive bias against Christianity. That's why we see a correlation where Christians are more likely to be conservative in some countries. This does not imply that Christianity contains conservative values, in fact it contains a number of progressive values (which I'll show later). This is not surprising when you realize that Christianity developed during the socialism of the Roman Empire. It was also developed by slaves and poor people. Being unable to deal with the cognitive dissonance, conservatives imbue Christianity with their values.

There are plenty of countries, like in Latin America, where people are very Christian but at the same time vote for socialism and progressive values. Further, history shows Christianity is a terrible defense against Islam. The crusades only started after muslims had conquered 2/3 of Christian land and where focused on Jerusalem, so pilgrims could make their travel.

Here's some actual Christian values, which in my opinion are progressive:
- "virgin birth"; Mary cheated on her husband, progressives don't have the instinctive drive to be monogamous that conservatives have.
- "Jesus died for your sins"; original sin and victim culture, victim culture is very popular with progressives and feminists. But the original sin of being white or male is also being pushed.
- "Turn the other cheek"; avoid conflict/competition
- "He who is innocent throw the first stone"; we'll apply the law when it suits us politically
- "Repent and you will be forgiven"; Easy forgiveness so long as someone holds the right political position
- Christians took the sacrifice of Jesus as a replacement of the animal sacrifices they'd been doing. Requiring less investment, less commitment to morals, only professing to believe, is progressive.
- Jesus glorifies self-sacrifice, which mentally primes people for socialism.

Islam does have conservatism, I don't know about Judaism. But Christians don't actually follow any of the Jewish rules, so can't claim those values.
