Pseudoscience and official science

Many investigators that work in pseudoscience often act in the contrast with the official science. And the terms science and pseudoscience are usually used as the antonyms. Researchers of pseudoscience consider that the representatives of the official science such as the members of the organization on the fight against the pseudoscience keep the group interests and are politically obeyed, don't want to admit their mistakes and as a result fight for the ancient views on the world forgetting about the truth that is kept by their theory.
Pseudo-scientists may really use and give the real examples from the far away past when the scientists that were giving the revolutionary ideas for their time were scoffed at and were even put into the prison. The most frequent example is the destiny of Galileo Galilei that was accused in blasphemy because of his scientific theory that contradicted the knowledge of that time. A great number of scientists also had the similar destiny.
Some researchers of pseudoscience even remember the political regime with the sciences. They remember the oppression of the genetics in the former USSR. But such compare has no background. In such way the oppression of genetics was organized not by the scientific society but by the political ideology. And the famous scientist Galileo Galilei was persecuted by the Church Authorities but he was one of the most respected authorities in the scientific society of that time.
