A week after firing commentator Sandra Tsing Loh for uttering an obscenity in a commentary, the Santa Monica public radio station KCRW offered her her job back. “Late last week, station General Manager Ruth Seymour apologized to Loh and reversed her decision to terminate the commentator for using a four-letter obscenity on KCRW-FM (89.9). But Loh turned down the station’s offer Monday, citing what she called a “toxic” environment there.”
