This is a bit too loose for me. Fascists want one party and will use political violence to suppress opposition. Again, Republicans are on the right, so are fascists, of course you are going to find similar ideas. Police are not above the law in the minds of Republicans. They will error on the side of defending the policeman, but almost all of them are more than willing to admit policemen make a lot of mistakes, and if the evidence is there, they agree they must be held accountable. Hostility towards trade unions can be rooted in multiple political philosophies including libertarians.
Trump pardoned Joe Arpaio --- that's quite literally placing him above the law. Trump being the highest ranking member of the Republican party would suggest that police are above the law in the minds of Republicans. Joe Arpaio was
not held accountable. More broadly, police
unjustifiably kill dogs and people every single day and receive, as consequences for their actions,
the long arm of the law a paid vacation. Okay, okay, I'm being unreasonable.
Some of them receive legitimate punishment for their crimes, but not nearly to the extent of being 'under' the law as they should be.
Republicans are super into union-busting, but have they ever said a single bad word about police unions? Nothing springs to mind.
Republicans support many things that would disproportionately harm minorities. The way many on the far left imagine republicans think about minorities is simply false. They are generally not explicitly discriminatory in the way a true fascist would be. The things Richard Spencer is saying are not mainstream republican ideas.
If the ends are the same, do (perceived) differences in attitude really matter? Generically Republican ideas about minorities may not be on the same
scale as Richard Spencer, but it's a spectrum, not an on/off switch, and they're still on that spectrum.
I don't understand the distinctions between being a committed fascist ideologue and be an actual existing fascist. Fascists are committed to fascist ideologies, if they aren't, then they aren't fascist. I'm not saying they have to identify as such, but their beliefs have to correspond with all necessary fascist tenets. You should be able to read a list of your tenets to them, without identifying them as fascist tenets, and they should say "Yes, I support those things". I'm certain that isn't the case for most republicans, even with the (IMO relaxed) criteria you used above.
I'm less than certain, and one can certainly enable by tacit support, compliance, or simple silence without being a true believer. Since we're talking about fascism I hope it isn't invoking Godwin to remind that the Nazi Party was a
minority in Germany when it took absolute power. The conservative party did not say "Yes, I support those things," but it did say "I don't mind."
edit to avoid double posting
Immigrants do not have an inherent race, by the way.
This is a nice, factual statement that, unfortunately, has no bearing on the political reality of immigration. Which, by the way, is inherently about race.
Also, to address a point raised earlier by a user whose name I cannot recall,
illegal immigrants commit less crime than the native population, because, duh, they don't want to draw any attention to themselves and get deported. That they are here illegally does not mean that they are here to commit crime.
final edit: to make a comment on-topic

I agree with OP or the first few pages of the thread in that OT is in a good place right now. It could be better, but it's
been worse. Also, I believe the 'like' button to increase user engagement and sociability.
