Did a little looking and around, and you should not worry too much about this dude. He recently attacked Putin as being too soft, and got fired from his job. I will give the author some slack on this, he wrote the article a few months ago. However, I tend to use Occam’s Razor on these matters, look to the obvious instead of dark forces working from the shadows.
The one mistake in the article is to focus too much on Dugin, when, actually, he is an ideologist and a leader, yes, but only part of a larger movement. He was replaced by Vladimir Zhirinovsky, who wants to deport the Jews and encourages his aids to rape "anti-Russian" journalists.
Other guys like Sergei Kurginyan and his "Essence of Time" weirdo movement are still around too.
Dugin was let go because he was getting too much attention from the media, and had become the subject of books, hence undermining the Russian war effort in Ukraine. If Putin did not want Dugin around, he would have him arrested too like he ordinarily would.
Another comment here I forgot to make. The dark forces thing was a discussion from some other writer (actually, it is a literature paper tracing occultism in Russian popular culture), if you click the link. The U.S. has occultism in our popular culture pretty heavy too, to be fair, but the overall point was that Russia is hardly a Christian paradise; and, two, their occultism is even creepier and scarier than ours, insomuch that it is a view held by people in positions of influence, of which Dugin was only one.
I think it would be a stretch to go from this to a "satanic conspiracy." But the comparison between Russia and these mystical nationalists with their interest in "volkish" religions, and Nazi Germany and Hitler's interest in the same, is worth considering when thinking about the route Russia is going in as a country.
Bottom line: Do not believe the stupidity about Russia becoming a Christian empire.
