Plato was known for his strong opinions and criticism of other philosophers, including Protagoras, Heraclitus, Parmenides, and even his own student Aristotle. In his works, Plato portrayed these thinkers as holding views that were different from his own and challenged their beliefs on various topics.

Democritus and Plato had differing views on the nature of the universe, with Democritus being more materialist and Plato believing in the existence of abstract forms. It is possible that this difference in views contributed to Plato's call for the burning of Democritus' books, but it is not the sole reason.
