Your question is somewhat poorly framed, as it uses terms (such as “scholars”) while not defining what one means by the term; and “majority”.
The silliness of the Jesus Seminar has not been something new; a goodly amount of what they did and believed goes back to the very late 1600’s and forward. No one has ever, to my knowledge, taken a poll of who believes what; most of that can be determined by reading the professional works that individuals have published.
One poster blames this all on Muslims. I have no idea if Muslims have waded in on the matter, but the underpinning goes back through non-Muslims.
One allegedly can ascribe to themself the title “Scholar”, and unless someone else comes along and debunks the title, it will carry some weight among some people - particularly among those to whom th works of that individual appeal… So if someone does not believe what we profess in the Creed, they might take strongly to an individual positing that Christ was not actually killed by the crucifixion. As an aside, one can get a degree in theology (as in a Masters or PhD) without having to process that they believe what the Creed states. That then would likely qualify them as a scholar.
In all likelihood, those individuals supporting the "work’ of the “scholar”, like the “scholar” do not believe that Christ was God incarnate, do not believe that He was the second person of the Trinity, and will attach to any cockamamie theory to support their lack of belief. and among them may be some Catholics, people who were once upon a time baptized, but who somewhere along the line either did not accept the teachings of the Church, or parted company with those beliefs.
So to answer your question, undoubtedly there may be a few individuals who have garduate degrees in theology (largely, but not exclusively Protestant) who believe thw swoon theory and anything else which gets tied to it.
They have no faith (by their own profession) and have no credibility among those who have faith.
