== Abusive fallacy? == 

 I don't think that this is a proper fallacy in the sense that name calling is hardly used as an argument when it happens. There should be a strong distinction made between "I tell you that you are stupid because I think it and want to express it" and "I tell you that you are stupid implying that I am right and you are wrong because you are stupid". 
 Is there any proper reference about this specific subset of the argumentum ad hominem? I visited this page quite often and I remember not seeing this. I am suspecting that someone with a personal agenda added it to the list knowing (hoping?) that it would be used by people to completely void and close arguments when name calling starts happening. This is a very annoying tendency of people to start completely throw out perfectly sound and logical arguments because it is accompanied by name calling. I think there is a name for that. 
 I would like to see a reference supporting this fallacy.
