The playwright Neil LaBute is not known for beating around the bush or for having a feather-light touch regarding hot-button topics. Instead he revels in making his viewers squirm in their seats, question their egos and formulate panicked confessions. In his latest work, "Filthy Talk for Troubled Times: And Other Plays," he airs his earliest play, a series of vignettes told by characters hanging out in an American barroom, and other more recent works.
