To understand this we need to go to the source https://en.wikipedia.org/wiki/Meme#Origins - ideally the reader of this post should know or least understand the premise of the "Selfish Gene" theory..
Religions are collections of self-referencing memes and while Genes program us on the most basic instinctual level, memes are largely responsible in programming our subconsciousness(once's we are old enough) thus the behavior of a child is almost entirely driven by Genes while the behavior of an adult is almost entirely driven by Memes(acquired experience).
Thus Memes to a large degree override Genes in later states of life.. and what is christianity if not the worship of a jewish god?
Virtually all of our decisions are made by our subconsciousness and we only get to understand them(if we are lucky) consciously. Thus a christian will be constantly driven by his subconscious(Meme driven) desire to fulfill the "Biblical prophecies" even at the cost of his own life. Remember Genes/Memes do not care for the survival of the individual only for the "greater good" ie. their own propagation. If it was otherwise no life could ever go past the bacteria stage. The book "Selfish Gene" also talks and explains this in more detail.
So as long as (Judeo-)Christianity is the main prevailing religion of the West we will never be able to beat (((them))) simply because our own subconsciousness won't allow it as it would go against it's basic survival programming. If say all jews where to die out(under any circumstances) or if jews where to lose their "god given country" or if any other major judeo-christian theme where to be disproven than ALL of Biblical prophecy would be invalidated and the Christian-Meme-Complex would die and that is obviously something a Meme would "do" anything to prevent.
And that is why so many christians where betrayed by their own subconsciousness and their own christian-brothers and sacrificed to keep the Christian-Meme-Complex alive - because that's what self replicating units of information do - they ensure their own survival by any means necessary.
And that is also what parasitical relationships are based on, the parasite often "injects" a part of his own information-complex into the host to make him dependent on it for his survival(or make him think that), say like a drug-pusher would acquire customers by handing out free samples, or how a cigarette company would get more people to smoke by advertising etc.
By infecting Evropeans with Christianity the jews have made us "dependent" on them for our moral and spiritual framework - and we will never be able to shake (((them))) entirely off without shaking off this (Christian)Infection.
