So.
By the end of the 19th century the research of Hungarian prehistory was monopolized by linguists, whom represented the Finno-Ugric research line, after they won the so called Ugric-Turkic War (this war was a heated discussion between researches about the origin of the Hungarian language, is it Ugric or Turkic). Since the topic is prehistory, no historical sources are available so historians generally could only chime in from the sideline. The other science that could really help, archaeology was also subordinated to the linguistical line, and put to work to find material proof of their theories (and stop creating their own theories deduced from the material they found). There were sharp exchanges, like "historians shouldn't play linguists" said the ones, and "then linguists shouldn't play the historian" came the reply from the other side (note: these were official researchers).
These researchers consciously made exclusions during their studies, for example they made geographical exclusions, the Hungarian ancestral lands or even related ethnicities couldn't be searched south from the 50th parallel, or further east then the Ob, and if you were an archaeologist for example who dug - let's say - in Kazakhstan and said "hey, I found something that could be related to Hungarian prehistory", then your fellow professors (archaeologists, linguists, historians) in their publications would label you dreamy, romantic, dilettant, imbecile, etc. - most recently: pseudoscientific -, and say you produce far-fetched fairy tales, instead of scientific work. Your work would be shut down, if not sacked outright then sent to bumfuck nowhere to a minor position, no hope for promotion, if member the HAS (the Academy previously mentioned), then your membership cancelled, etc.
They also created dogmas, questioning them resulted in the same treatment.
Now.
As I said the alternative theories include a variety of colors, and aspects. From the simpler Turkic line, to such ideas which try to find our origins on Antlantis, Mu, and the Sirius. From the suggestion that the Huns and Hungarians might have been related to stating that Jesus was Hungarian this one is actually true ofc. And it's easy for the "academists" to lump everyone together and say "he is sumering again" made up verb from Sumer, is really in use IRL.
Luckily times are changing and some aspects of certain topics can be questioned or put in different light.
