And that means what, exactly? Many people read the words of ideologically evil people in order to better understand the evil philosophy and therefore better recognize it if/when it raises its ugly head.
I used to listen to Radio Moscow during the era of the USSR for exactly that reason. It didn't mean I turned doe-eyed every time I heard the propaganda, it meant that I was becoming educated. So that when I hear the same language from American Democrats, I recognize its source and know that I should stand against them.
If people do NOT study the words of evil and understand the underlying assumptions and philosophy, they are quite likely to fall for it. Case in point: look how many liberals are swooning over the idea of opening the borders and allowing unfettered illegal immigration. They really believe that unfettered illegal immigration improves the lives of the illegals and does no harm to the owners of the country. It takes careful intellectual examination of the issue (something liberals are not capable of) to understand the many ways in which that utopian ideal is not, and never will be, an accurate picture of reality.
