What is this lie about?
I simply went through all of this myself – first, you become fascinated by some concept, but the more you examine and study it, the more contradictions you find in it, and over time you realize that almost everything is wrong.
This does not mean that such concepts should not be studied – on the contrary, it is very useful, as it develops the mind, especially through overcoming one's own misconceptions. Besides, these concepts, although to a small extent, contain some truth, which must be separated from everything else and boldly used.
One of the most well-known examples is the alternative historians Suvorov and Fomenko. At one time, they were very popular, but time has put everything in its place. There are valuable ideas in their works, and they openly declare and illustrate with their own example the most valuable one – that history is an object for manipulation, often quite brazen, so it should be believed very cautiously, and one should try to study different sources.
