Tip: "Birtherism" is most effective when used precisely — reserve it for situations that genuinely call for the sense of "a movement in the united states of america that doubts or denies that the 44th president, barack obama, is a natural-born u.s. citizen, thus implying that he is ineligible to be president" rather than reaching for it as a filler word.
Usage: "Birtherism" is primarily used as a noun. Its central meaning — a movement in the united states of america that doubts or denies that the 44th president, barack obama, is a natural-born u.s. citizen, thus implying that he is ineligible to be president — makes it most effective in contexts where precision matters over a more general alternative.
