I agree the term is far too broadly applied, but Fascism is not synonymous with Mussolini. The Wikipedia page you link to also categorizes Nazism is one kind of fascism.
The word Fascism may today primarily conjure images of Hitler and the Third Reich, but in the thirties it was strongly tied with Italy as well.
Anyway, I think the fine line of disagreement here is that I personally see "Nazi apologist" as someone who is an apologist for _all_ of National Socialism, not just certain policies. You may be correct that today, people could consider anyone who's denying the holocaust to be a "Nazi apologist."
Does that make sense?
Fourteen Defining Characteristics of Fascism
Dr. Lawrence Britt studied the fascist regimes of Hitler’s Nazi Germany, Mussolini’s Fascist Italy, Franco’s Spain, Salazar’s Portugal, Papadopoulos’s Greece, Pinochet’s Chile, and Suharto’s Indonesia. He found fourteen defining characteristics common to each.
Powerful and Continuing Expressions of Nationalism — Fascism makes constant use of patriotic mottos, slogans, symbols, songs, and other paraphernalia. Military pride and unity are encouraged. Flags are everywhere, as are flag symbols in public displays, or pinned to clothing.
Disdain for Human Rights — These are viewed as a hinderance to achieving their goals. Through propaganda, the population is made to accept this abuse by marginalizing and demonizing those being targeted. Tactics include secrect, denial, and disinformation. The people ignore or approve of torture, assassination, incarceration without formal charges, etc.
Identification of Enemies/Scapegoats as a Unifying Cause — The people are rallied into a unifying patriotic frenzy over the need to eliminate a perceived common threat or foe: racial, ethnic, sexual or religious minorities; liberals; communists; socialists, terrorists, etc.
Supremacy of the Military — Even when there are widespread domestic problems, the military is given a disproportionate amount of funding, while domestic needs are neglected. The military is glamorized, and used to assert national goals and intimidate other nations.
Rampant Sexism — The governments of fascist nations tend to be almost exclusively male-dominated. Under fascist regimes, traditional gender roles are made more rigid. Divorce, abortion, and homosexuality are suppressed and the state is represented as the ultimate guardian of the family institution.
Controlled Mass Media — Sometimes the media is directly controlled by the government, but in other cases, the media is indirectly controlled by subtler government regulation: the control of licensing and access to resources, economic pressure, appeals to patriotism, and implied threats. Censorship is very common.
Obsession with National Security — Fear is used as a motivational tool by the government over the masses, and questioning its activities is portrayed as unpatriotic or even treasonous.
Religion and Government are Intertwined — Governments in fascist nations tend to use the most common religion in the nation as a tool to manipulate public opinion. Religious rhetoric and terminology is common from government leaders, even when the major tenets of the religion are diametrically opposed to the government’s policies or actions.
Corporate Power is Protected — The industrial and business aristocracy of a fascist nation often are those who put the government leaders in power, creating a mutually beneficial business/government relationship and power elite, especially in the repression of the poor.
Labor Power is Suppressed — Because the organizing power of labor is a threat to fascism, labor unions are either eliminated entirely, or are severely suppressed. The working poor form an underclass, and are viewed with suspicion or outright contempt. Under some regimes, being poor is considered a vice.
Disdain for Intellectuals and the Arts — Fascist nations tend to promote and tolerate open hostility to higher education, and academia. Professors and other academics espousing unorthodox ideas are censored, harassed, or arrested. Free expression is the arts and letters is openly attacked. Art and literature serve the national interest, or they don’t exist.
Obsession with Crime and Punishment — Fascist regimes, the police are given almost limitless power to enforce laws. The people are willing to overlook police abuses and even forego civil liberties in the name of patriotism. There is often a national police force with virtually unlimited power in fascist nations.
Rampant Cronyism and Corruption — Fascist regimes almost always are governed by groups of friends and associates who appoint each other to government positions and use governmental power and authority to protect their friends from accountability. It is not uncommon in facist regimes for national resources to be appropriated or even stolen by government leaders.
Fraudulent Elections — Sometimes elections in fascist nations are a complete sham. Others times elections are manipulated by smear campaigns against or even assassination of opposition candidates, disenfranchising oppositions voters, use of legislation to control voting numbers or political district boundaries, and manipulation of the media. Fascism uses the judiciary to manipulate or control elections.

Address a couple of your points:
Fraudulent elections: not all forms of government are duly elected by a people, but there is generally some process of a decision making body coming together that can be called "elections". And this process is always ripe for manipulation. I think one could resonably point to the Reichstag Fire and its political fallout as suppressing the German Communist vote and was a form of fraudulent electioneering.
Labor power is suppressed: There is a well documented history of forced labor within Nazi Germany during WWII. It is one of the reasons the German War Machine held on as long as it did despite heavy allied bombing and sabotage. http://en.wikipedia.org/wiki/Forced_labour_under_German_rule...
I think it is reasonable to say the individuals in these camps didn't have access to the benefits of free association and what in general terms a strong union and workers rights oriented economy would provide. If we can't call that a form of "suppressing labor power" then what would you suggest we use to describe the phenomenon?
