It's better (although it still fails to reject an argument on its merits, or lack thereof), but I'm not sure the term can really be rehabilitated in such a manner. First, the connotation has already been established among too many people, and it's bad, and second, most of those I've encountered who use that term write it as `splaining.

It comes across less as addressing a problem and more as hiding it. It becomes a code word - whitewashing the explicit sexism, but maintaining the implicit.
