If an author had evidence for something that would overturn conventional thinking in this matter, and immediately make him or her famous, then he or she would write nothing about it, to stay in the club?
No, despite Scott Wolter's wishes to convince the world that such is the case; most such cases are rather benign.
This isn't a Tom Clancy novel or Indiana Jones movie.
Most people in academia react to controversial ideas about as flustered as Spock to an interesting proposition.
Which, in one quite entertaining episode of America Unearthed, Scott Wolter attempts to convince a town museum curator & historian that a structure in the town is proof of the Knights Templar being in the town, and the curator simply just smiles a bit and says that he disagrees, but he's willing to test the idea if Scott has any propositions.
That's pretty par for the course; not the heated (smalltime) celebrity historian throw-downs that get the attention occasionally.
So, no; no one would hold back from writing a paper for fear of ridicule like that over something like this.
On some other matters; yep, this kind of implied bullying occurs and it's really sad that it does.
Jesus, sorry to say, is too unimportant to History (not religion...History) for anyone to care about pressuring someone in the field from writing in opposition to the standard view.
The kinds of things that get this treatment is the theory of ________ (dammit...sorry...my brain is "farting" on me at the moment as I stayed up all night playing Fable 2 for the first time...yes, for the first time [hey, it only cost $3!

])....
Well, either way; it's a theory that states that Ancient peoples from all over the globe had been traveling back and forth to the Americas (North and South) for a very long time and that the Americas were not closed off from Asian or the Mediterranean (some also toss in African) societies completely, and the theory stretches to a variety of date "claims" (propositions).
This idea is pretty hot, and many won't touch it.
The reason for this to be a hot item and Jesus not to be is for a simple reason: if Jesus doesn't exist, it affects the Historical, Archaeological and Anthropological record about this much:
However, if the theory of Ancient peoples traversing to the Americas were to be right, then it would affect the Historical, Archaeological and Anthropological record about this much:
The amount of rewriting text books, and re-cataloging the archaeological record would be massive and a ton of work; not to mention, absolutely destroy tons of papers and academic publications' stances regarding the reality of human history.
And because of this; this particular theory gets allot of resistance - at times, people can be denied museum access (and have been many times).
But Jesus?
No...no one really has to redo a crapload of work if that standing changes.
