Is a Rush Limbaugh dittohead really the same as a Nazi?

No, a Rush Limbaugh dittohead and a Nazi are not the same. A dittohead is typically someone who strongly supports Limbaugh's conservative viewpoints and often agrees with his commentary. In contrast, Nazis were members of a specific political party in Germany responsible for horrific acts of violence and genocide during World War II. While both may hold extreme beliefs, the contexts and implications of their ideologies are fundamentally different.
