I really don't want to waste time arguing against anyone, but for those here capable of influence on this issue, I'll counter your views once. Sorry, but I think your reasoning is completely backwards concerning the interpretation of Bible scripture literally or allegorically. My explanation depends not on well researched studies and references but upon common sense and some basic Bible reasoning.
Concerning man-made interpretative judgements of written or spoken information, I am quite confident that rational people go through life taking most such information literally, not allegorically - unless the context or style suggests otherwise. Whether its someone calling you to dinner, an ad listing something on sale, or an article telling you so and so got arrested last night, we are bombarded with hundreds of statements each day. Life would be a madhouse if we allegorized these statements or events by default. I'd go so far to say that we couldn't function or live rationally under such premises. No one could believe, understand, or interpret anything because there would be no objective reality.
To suggest that a literal interpretation of information is subject to more man-made subjectivity than an allegorical one is equally irrational. Why? Because a simple, literal interpretation has a "most likely" intended meaning, whereas allegorizing opens up opportunity for all kinds of theories. This could be done with nearly any sentence or idea no matter how simple and obvious the intent is, but here's one Biblical example. The Genesis creation account is pretty simple if you interpret it literally. Even a child can read and understand what it says about the occurence and timing of events. In other words, if you take it literally, there's one general account option. For those (many) that reject the clearly written words, at least four major alternative theories have been developed which allegorize (or otherwise dismiss) the clearly written account. You mustn't even choose sides to see that a literal reading of the text offers less opportunity for man made, subjective error than a multitude of alternative theories based upon allegorization.
As you've suggested, you can allegorize away any miracle that Jesus did, giving countless theories of what really happened. That's what skeptics do with every supernatural or disliked event in the Bible. But, they don't do that with other historical documents. It's telling that the standards used by skeptics for interpreting (or believing) the Bible are not consistent with their determination of other historical works. There's no justification for this other than a predetermined bias against anything supernatural.
Concerning Jesus' post-resurrected supernatural body, the Bible shows us how He was both body and spirit, not just one or the other. Luke 24:36-43 makes this clear with convincing specificity:
While they were still talking about this, Jesus himself stood among them and said to them, “Peace be with you.” They were startled and frightened, thinking they saw a ghost. He said to them, “Why are you troubled, and why do doubts rise in your minds? Look at my hands and my feet. It is I myself! Touch me and see; a ghost does not have flesh and bones, as you see I have.” When he had said this, he showed them his hands and feet. And while they still did not believe it because of joy and amazement, he asked them, “Do you have anything here to eat?” They gave him a piece of broiled fish, and he took it and ate it in their presence.
There is no contextual, structural, or grammatical reason to allegorize this account of Jesus' first meeting with the apostles. Those who do, do so merely to dehumanize Jesus or to dismiss the supernatural event altogether. I'd suggest that such tactics warrant no respect since they go against the evidence - that being a historical document based upon eye witness accounts.
Although I think it's tragic to reject God and His written word in the Bible, I accept it as one's choice and will of the heart. But justifying one's unbelief by dismissing or misinterpreting what the Bible says? I'd call that foolishness - believing what you want the Bible to say rather than what it actually says.
