I have no idea how "intolerance" is remotely coming to overlap "white" or "American" except in the delusions of some fringe lunatics who believe both that Confederate statues must remain up (to protect heritage) and also history about black people must not be taught.
Sometimes you'll hear it expanded as "The Fine Article" or just "The Article".
Often, it really does mean just "the article". People use the acronym without expanding it out or thinking too deeply about it. At one point, decades ago, it may have connoted some kind of hostility (e.g. "If you had read the f---ing article..."), and it's still meant that way in "RTFA" (read the f---ing article, meaning "that was already answered, so you clearly haven't read the thing that we're supposed to be discussing")
But now, it's mostly just a kind of in-joke, and TFA means nothing more than "the article", with the F entirely silent.
