The McMinnville picture is fascinating but cannot function as any kind of real evidence, and maybe even that is Randall's point in his blog post. We'd need more pictures from independent witnesses for these pictures to warrant the claims that have been made about them. This pattern of consistently leaving only suspect evidence means either the UFOs somehow know when it is safe to appear and when it is not (it is a part of the phenomenon), or that the alleged pattern of the UFO experience is imaginary (there are no real UFOs).
It doesn't seem reasonable to me to believe that all UFO reports are the result of misperceptions, hallucinations, illusions, hoaxes, whatever else the case may be, and there are a couple of good reason for that. The first one is that investigation into reports indicate that after those possibilities have been eliminated, there is a residual portion of reports that cannot be reasonably explained as anything else. Add up the details of those reports and the only way to dismiss them is to simply deny they're real or accurate, which might be reasonable if there were only a couple of such reports buried in the distant past. But that's not the case.
But even if one doesn't want to look at the documented reports and case studies, there is still the firsthand experiences of those people who have seen a UFO well enough to be sure beyond any reasonable doubt that what they saw couldn't be anything but some sort of alien craft ( Note that alien doesn't necessitate ET ). It might be reasonable to offhandedly dismiss a few reports, but after so many instances it becomes unreasonable to think all the witnesses are either incompetent or liars. To do so is IMO the height of arrogance. Hynek eventually came to understand this, and he was a genuine scientist with impeccable credentials who was directly involved in UFO research.
Now all that being said, I still think your other points are valid. I would even go so far as to say that at this particular time, perhaps there are no alien craft visiting our civilization. I don't know for sure. I just know what I saw, and if I saw a UFO I'd have to be completely self-centered to think I'm the only one in the world out of thousands and thousands of people who isn't lying or misidentifying what they saw. Other people must have seen them too, but the trick is knowing who, and that's where your focus on evidence comes in, and believe it or not, I appreciate that you want some convincing evidence. The last thing we want is people who look at the subject without some critical thinking skills.
