I think many people would argue that the violation of constitutional rights in the name of "national security" is something that would be done by a fascist.
Lincoln wasn't a fascist. The word hadn't been invented.
Socialism actually has a definition, current literature, etc.
My point? When I say someone is a Socialist, that means something. It means that they support Marxist economic policies, probably with some modifications, e.g. "Social Democrats" in Europe.
When I say someone is Authoritarian, that has a simple, dictionary meaning:
1. favoring complete obedience or subjection to authority as opposed to individual freedom: authoritarian principles; authoritarian attitudes.
2. of or pertaining to a governmental or political system, principle, or practice in which individual freedom is held as completely subordinate to the power or authority of the state, centered either in one person or a small group that is not constitutionally accountable to the people.
Now if someone favors a "living document" interpretation of the Constitution, and strongly opposes judges with a philosophy that looks for the words and intent of those who wrote and amended it, that, to me, means that they oppose accountability of the government to the Constitution as amended. It's pretty clear. Most Democrats fit this description. RKBA is probably the best example, where the idea of the right being a "collective right" only for militias was
made up by the "living document" crowd in the mid-20th century, and is being used right now by many "progressive" politicians in an attempt to circumvent a Constitution they find inconvenient.
As far as individual rights, apart from the right to privacy WRT abortion (I have no problem with that), yes, most Democrats do favor some individual rights. They don't, however, often favor applying the same principle of privacy to firearms, political speech, drugs, cash transactions, etc. And taxation is, by nature, a violation of individual rights. More taxation is a greater violation, less taxation is a lesser violation.
Like I said, the words have meaning that is different from tossing around "fascist" or "nazi."
I am not supporting the GOP here. That's not my point.
John McCain is an Authoritarian, too, BTW, though not a Socialist or a Social Conservative, either. Bush is a mixed bag, realistically. Demonized, yes, but no more deserving of it than a number of others. Guiliani appears to be a mixed bag, also, in a different way. Hillary Clinton is probably closer to "fascist" than Bush, actually, as she is a DLC corporate Democrat, with Authoritarian leanings. But that would be the real meaning of the word, and it's really a dead movement, politically. At least there are few conscious "fascists" in the world, whereas there were real Fascists in the 1930s and 40s.
