You have to understand these Jews have a culture of lying and manipulating goyim, you are never going to convince them that Jews were the bad guys,they already know that and the purpose of their talking isn't to come to a consensus about history, it's about trying to get people to attack and demote and fire White people so they can have control over Western institutions.
And the people that they are usually trying to rally to be hostile to Whites do not have a significant attention span. If you give them a book to read about the subject that proves the Holocaust as presented by Jews is fictional propaganda, they are not going to read it.
When talking with most people you have maybe 15 seconds to make a point that will wreck the arguments of the anti-Whites.
So another way to do that, using "Whataboutism", you just inject, "Well, what about the apartheid against the Palestinians and stealing their land?" Then if anyone wants to refute that, they have to talk about Jews killing Palestinians, keeping them in concentration camp cities, testing weapons and crowd control strategies on them, building walls, white phosphorous attacks on Palestinians, etc. and as long as the discussion is about that, they have already lost the debate.
I think the internet exposing the inconsistencies of the Jews story is wonderful because it shows they are liars.
But when you are on the defensive like that, you are presenting yourself from a defensive position and you only appear as the good guy if your audience has the attention span to understand that you are presenting proof the Jews lied.
If you want to be effective in a sphere of information you have to use arguments that are appropriate for the people you're talking about.
In online communities where you have high attention span people that can dig into material, exposing the lies of the Holocaust in great detail is wonderful because it convinces the high IQ people that without a doubt they have been lied to by the Jews. But in most settings you've got 15 seconds of attention to flip the Jews' anti-White rhetoric on its head and you need something simple enough to remember that everyone that hears you say it can pull it out of their pocket over the dinner table or with their co-workers to change minds.
