At what point did Jews spend "centuries" killing off Christians?
The reality is that Jews did spend the better part of 1,000 years doing everything they could to exterminate the old gods of Europe. They may despise Christians, but they never tried to exterminate them. The reason is simple:
Jews do not destroy what they can subvert.
Christianity is a Jewish tool to subvert whites.
The natural state of a civilized nation is "soft" monogamy. Most people don't realize this, but prior to about the 18th century, infidelity was much more narrowly defined than it is now. The reason is that men have always had the conqueror's genes - conquest by rape is our most common way of destroying a competing ethnicity or culture. Christianity was designed to slowly erode this state of affairs and replace it with one where male sexuality and marital fidelity were considered equivalent.
Even now, after centuries of being shamed for our natural instincts, men, even married ones, still check out other women. It may be suble, or it may be obvious, but any man who tells you that he never notices how attractive the women are that he's talking to is either a eunuch, a faggot, or lying. This instinct isn't just "men beng pigs" as the Jews would have us believe. Remember, even the Ten Commandments of Moses commanded not against fornication, but against coveting another man's wife. That has always been the issue: a woman who is not married, and is not chaste, has been fair game to anyone who can have her; it is only the wives of men, or the women who seek to be future wives of men, who were preserved. That is why the penalty for defiling a virgin, in the old testament, was to marry her; that is why the prohibition was against coveting other men's wives - because women only have use as wives and mothers. Slatternly women who choose to give up their virtue to a man whom they weren't married (or did marry afterwards, at the very least) have no inherent social value. They were preserved, as part of the weaker sex, but to depredate them sexually, by force or by seduction, was considered, at worst, a minor social faux pas - a non-issue; and if their liaisons got them with child, at least they were serving some useful function, even if it was inferior in nature.
As our world has become more "civilized", men's instincts have not changed. We still want what we once had, because we were born and bred to it by 1,000,000 years of evolution. First, the Jews eroded marriage by making divorce an accepted concept, using Christianity as their proxy; then they changed the definition of male fidelity from loving and protecting his wife, and marrying no other, to a complete identification of male sexuality with male fidelity; once we were primed by this assault upon our natures, they worked to increase the "age of consent" from 12 or so up to 18, with no upper bound on the age at which a woman can accuse a man of rape if she is under the influence of alcohol or even feels "pressured" somehow. Now that these goals are complete, they turn their attentions to the last bastions of male sexual conquest: porn, VR, and sexbots.
Porn was men's solution to the problem of having instincts that they were taught were evil, base, animal, or sinful - they decided that if they could not fuck the maid, they could at least pretend to in their fantasies. Giving white men even the refuge of their own minds is unacceptable to the Jew, however, and they have pursued the male tendency toward sexual conquest even into the realms of our imaginations, our fiction, and our machines.
Of course, most of the emasculated little fucks here won't read my entire post, and certainly won't analyze it critically. I just hope at least one of us are capable of indendent thought, still.
tl;dr: fucking women who aren't wives and aren't preserving their virtue (to become wives) was never considered "bad" until the Jews convinced us it was.
