Nobody important, really. She's Laura Schlessinger, a US radio personality who dispenses advice to people who call in to her radio show and writes various kinds of self-help books about families and relationships. I don't know if she's still on the air or not. She's generally sensible and admirably tough-minded, though the few times I've heard her program what struck me most strongly was what idiots most of the callers were, to be unable to figure out an answer to the kinds of questions she gets asked. Typical example: "I've just caught my husband having an affair for the third time since we got married ten years ago, he says he's broken it off now, swears he'll never do it again, and says he loves me. Should I believe him?" (D'uh! NO!)
She's also, she says, an observant Orthodox Jew. Her "taking on homosexuality" refers to a program from a few years ago in which she flatly stated that it's an abomination according to Leviticus 18:22 and cannot be condoned in any circumstances. She doesn't generally use arguments from authority like that; I think she just cherry-picked that one because it matches her position and it's easier than trying to make a reasoned case. I've never heard her suggest stoning adulterers to death as the OT directs, despite many callers making complaints about adulterous spouses.
