Is being racist, homophobic and monogamist and otherwise moralistic with some skewed morals enough to be called a fascist

Not necessarily (although it does make one a bigot), but taking part in an organised political movement to enshrine that racism, homophobia, and monogamism traditional marriage (that’s what I hear the Right refer to it as) into law and to advocate the use of violence to enforce their view of sex, race, and religion onto other people is fascistic. Think of it like a square and rectangle. All squares (fascists) are rectangles, but not all rectangles (right wing) are fascists. At the end of the day, fascists do need to appeal to a broad enough segment of the population beyond their most devoted base in order to gain power, so they’ll do that by appealing to common prejudices and fears held by people, which can in turn radicalise them further.

That said, people on the right wing or conservative end of the political spectrum who identify as anti-authoritarian still, somewhat hypocritically, tend to believe in hierarchical structures elsewhere, be it familial, economic, racial, or sexual. In fact, many libertarians and “anarcho-capitalists” simultaneously argue for increased police funding while complaining about government tyranny.

I do want to be fair to those who identify as being right wing but do honestly leave other people alone (like New Hampshire-style libertarianism), but I believe that a confrontation between their wish for small government and the broader goals of their other right wing allies is inevitable, and that they will either be forced to abandon their stated limited government values.

Anarchists have a long history of wanting to use violence to get out of an authoritarian system

Yes, and the rest of the anarchist movement has largely disowned anarcho-capitalism. Many political philosophies have long held that violence is justified when it’s an oppressed people trying to end their oppression.

From the wikipedia article on ancapism

In a theoretical anarcho-capitalist society, the system of private property would still exist and be enforced by private defense agencies and/or insurance companies selected by customers, which would operate competitively in a market and fulfill the roles of courts and the police.

A core part of political anarchism is the belief that capitalism is another unjust form of hierarchy that must be dismantled. Anarcho-capitalists, by definition, support an unrestrained form of capitalism wherein instead of using the State as a tool of violence through civil institutions like the police and military, corporations are able to do it themsleves by having their own private police forces and armies.
