Excellent. So it appears to me that the chin is fake and it appears to you it may not be fake, but you admit that it just might be fake. so both of us agree, the chin just might be fake. End of story.
Congratulations, Robert. You just admitted the conspiracy books have been lying to you. And that you were wrong to proclaim the backyard photos fakes initially.
You are now reduced to proclaiming only that they MIGHT BE fakes, and only that it APPEARS TO YOU the chin is fake. We are getting through to you, and you are making real progress on your path to recovery. (That's also an admission, whether you realize it or not, that you cannot prove they are fakes - only that, to you, they give the appearance of being fakes).
The next step is for you to admit they MIGHT ALSO BE REAL, which should not be too hard as it is implied in the MIGHT BE FAKE statement.
The final step is to admit there is no evidence of forgery. This is the biggest step, and admittedly, many people recoil at first from taking this step. You might approach it several times, then fall back away in fear of the outcome. Let me assure you the world will not end when you admit it, it just seems that way.
As a recovering conspiracy theorist myself, I wish you all the best in your journey out of conspiracy-ville.
Aside to everyone else: I think Robert will probably recoil from admitting they might be real, and instead insist they have already been proven fake - despite the fact that every expert who has ever examined the first-generation materials has concluded there is no evidence of forgery to be found in the backyard photos. I think an admission they might be fakes (and ergo, might be real) is probably as far as Robert is willing to go at this time, and as much of a concession as we can realistically expect). The whole belief system of many conspiracy theorists hinges on the backyard photos being fakes. See, Oswald himself asserted in custody that they were fakes, and if he was lying about the photos, then he could be lying about other stuff, like not owning a rifle, or not bringing his rifle to work, or not shooting the president. So they must believe Oswald was being truthful in custody and the photos are fakes as the alternative is too horrible to contemplate.
