Conspiracy theories do have a pseudo-religious character, but I'm not sure there is anything specifically Christian about the phenomenon. Many Christians, even conservative Christians, disagree with them. Conversely, conspiracy theories (albeit mostly different ones) are popular in countries where Christians are a small minority, see for example https://thearabweekly.com/why-conspiracy-theories-thrive-mid...
I intended to focus more on the fact that it's not simply just an "anti-Islam" intention.
The fact that there are a plethora of conspiracy theories in the ideology and that it's largely people who identify as Christian or are pro-Christian seem tangential to me.
