The way I see it, if they don't want to be called fascists then they need to find a new label that accurately describes their desired goals. As long as they keep hiding behind this preposterous cloak of "conservative" to cover for an extremely radical agenda, I will use the label "fascist" as it seems to be the most-fitting existing term.

Alternatively they can explain how their agenda differs from fascism, rather than most arguments being of the form that <fascist dynamic> is required due to <some perceived emergency>.
