Yes. As the linked page on genocides already has Nazis in it, I don't think I'm invoking Godwin by saying that anti-Semitic (and anti-other-minorities) jokes, caricatures, propaganda posters, movies, newspapers and so on played a considerable part in making a large part of the German population accept, try to ignore, or participate in acts of genocide. These things were organised to cover even children: In elementary school math books, there were problems along the line of "An asylum for x number of [insert offensive term for the mentally ill] costs y Reichsmark per year. How many German families could be supported by that sum, if one family needs z Reichsmark?"

Language does not exist in a vacuum.
