The use of the word "terrorist" is not a buzzword fallacy when the organization in question is actually a terrorist organization or when there is actually a tenable association. The word terrorist could be used as a buzzword fallacy, for example that commercial that tries to associate terrorism with smoking marijuana as if there was actually a tenable association to be had.
Using the word "Islamist" is not a buzzword fallacy when the person in question is actually an Islamist.
Stating facts can never be a logical fallacy.
It's only a fallacy when I attempt to associate these people or organizations with these words that have negative connotations when there is no association, I have stated quite clearly that this man is not a terrorist and yet you want to use me saying that he's not a terrorist as an example of trying to associate him with terrorism.
Associating Islamism with Islamist terrorism is not a buzzword fallacy because the two actually have a causal relationship. There is in fact a tenable association.
An actual example of this fallacy would be something like the Internet Freedom Preservation Act, I mean who can be against preserving freedom right? But wait the actual act restricts internet freedom, or how about the Patriot Act which would imply that opposition to the proposal would be unpatriotic. These are associating words with things in which there is no actual association, those are examples of buzzword fallacies.
Some other examples of this type propaganda would be terms; such as, pro-life and pro-choice or man made global warming and climate change. Or deliberately switching one word with a negative connotation with a word with a positive or neutral connotation; such as, extermination to evacuation, or terrorist to freedom fighter, or the inverse by changing a word with a neutral connnotation to a negative connotation; such as, automatic weapon to assault rifle.
I have not engaged in any of this type of thing. I have used the proper terms in the proper contexts. Quite frankly I don't think you even really know what the hell you're talking about.
