You're going about this the wrong way OP, but you have the right idea. I used semantics to my advantage that in actually, it's not even disingenuous and got normalfags to realize that the holohoax has more to it than just two sides to it. This technique has been so effective that I almost feel like I'm cheating when I do this. Allow me to demonstrate:
Normalfags are accustomed to hearing the word "holohoax exposure," so much so, that you see this in jew laws and bills. Jews hinge all of their holohoax exposing laws on the term holohoax exposure that you have to stop and think what that means. The term holocaust itself is invalid as it is a greek term and the jews basically stole it and slapped on their death camp myth. But that only brings me to my next and main point.
Normalfags which are unaccustomed to studying the holohoax -and thus do not know the ins and outs of the myth or otherwise they would already know it's fake- believe by virtue of the fact that they possess simpleton logic that holohoax exposure, and by extension holohoax exposers, means the act of or someone who does not believe that 6 gorillion jews died, etc. Again, stop and think, is that really what we do? Jews did die, but they weren't the only ones, but the reason they died is the part that's the lie. We're not denying that anyone died, we're exposing a half-century-plus old fraudulent victim-card creating narrative that the jews used for many reasons the least of which was to make money but to stigmatize NatSoc Germany.
So how do you go about using this? You tell normalfags and explain to them like they're five that there's three sides to "holocaust debate," those that believe no one died (specifically name them deniers), those that believe the drama plus savageness plus obscenely unrealistic death toll, and those that believe that "people" did die but their deaths have been used to make money (buzzword: profit) and demonize the "nazis" and this side just wants the truth of the matter. Then immediately explain that many good people have had their reputations and lives ruined because they just want the truth because so many people have made tons of money off of the drama. Once you explain that to them, they will be so receptive to learning more that you the rest is easy.
Immediately after that, begin dispensing easily digestible redpills. Name people like David Irving, the International Red Cross death toll, the "death camps" were on the side that communist russia took over, that the survivors stories directly contradict each other, mention the failure in the logic behind the alleged methods of killing plus torture. That's just the start. After this they will no longer look at it the same way because they had been so used to a false dichotomy.
tl;dr: tell normalfags that holocaust realists get the wrong reputation because holocaust profiteers group them in with "holohoax exposers" who are (insert buzzwords) disinformation weirdos that believe no one died and the camps literally did not exist or something. Once they realize that there's 3 groups of people and one just wants the truth so they can expose the profiteers, they will want to know more.
