They're in
NO WAY interchangeable, and it's blatant abuse of basic political science to lump different terms into a single basket just because one can't be bothered with distinctions.
"Liberal" for instance, to take another established term popularly perverted, means one who believes power derives from We the People, and not from an aristocracy or clergy or priveleged class. Liberalism is what built this country and wrote its Constitution. Nothing to do with political parties or "right" and "left". Some like
flacaltenn prefer to call this "libertarian" although "Liberal' is the older term.
That has nothing to do with, for example, "Democrat", which did not even exist then, and which is the name of a specific political party. As such it's a
practical vehicle to get elected, not the repository of some ideology. Billy Graham and Zell Miller are Democrats. Frank Rizzo and Ray Nagin were Democrats for the purpose of getting elected because they knew what vehicle would work. The Sheriff in my town was a Democrat running for re-election, then a Republican running for re-election. He won both times. Same guy. Arlen Specter was a Democrat, then a Republican, then a Democrat again. Again, same guy. That's simply a grand game of Whatever Works. In the case of Rizzo and Nagin, they knew running for mayor of their city involved two choices, (a) run as a Democrat or (b) lose. Just as their counterparts in their suburbs face the opposite dynamic. In the case of my sheriff I suspect he assessed at some point that one local party ran a better get-out-the-vote campaign than the other. Just as you buy a Ford or a Dodge -- they take you to the same place.
Won't even bother with your other lump-basket terms. That should suffice.
It probably won't.
