The name is unfortunate. In fact, a lot of the people who are labelled "PUA" do disavow that acronym. There is a reason that Vladimir used a real language description "people who have any real knowledge of these matters" rather than the label that you moved to even though the categories referenced overlap dramatically.

I try to avoid that jargon as much as possible - it's inaccurate and an easy target for abuse. Avoiding it requires more typing and somewhat more awkward phrasing. "Social dynamics" is often a useful phrase. I think I would accept nearly any alternative, even something arbitrary.
