In recent years, ideologists and activists of the movement, which advocates that from the point of view of morality, physiology and legality, romantic and sexual relations between individuals of the same sex are perceived as absolutely equal (and sometimes even superior) relations between people of different sexes. In their activities, these activists often cite a number of arguments that turn into slogans, on the basis of which they criticize opponents of the changes they require. Among such arguments, for example, "every tenth person is gay," "gays are born," "orientation cannot be changed," "homosexuality is found among 1,500 species of animals," etc. This report focuses on analyzing the validity of some of the claims used by these activists. The purpose of this work is to disseminate information, which is now becoming less and less available due to the political situation that has developed over the past decades.
