If commie is an insult gluk is a commie in every sense of the word.
okay so this is what i think you're saying.
"If the word commie can be used as an insult, then is it an insult in every sense of the word?"
If this is what you are saying, the answer is no. It can be used as a joke or among friends. It still has the historically negative connotation, which may make it SEEM like an insult when no offense was actually given. Depends on the context the word is used in. Certain words that may be considered insults can be acceptable within the right context. Take a fucking english class, jesus.
