I think you're imposing the way you see it onto the way everyone should see it. I said "bondage as practiced by Wonder Woman and the Amazons... ." I don't think they, or Marston, saw bondage in the same way that you do. The subversive message here isn't that bondage is good, but that bondage isn't limited to what you think it is.
As for it worrying you about there being dominants and submissives (and I don't think that's exclusively part of BDSM. People tend toward either one or the other and it's inevitably a part of every relationship, sexual or not, romantic or not), in Wonder Woman, the most evolved practitioners of bondage are what would today be called "switches." They enjoy and learn from being on both sides. In Marston's philosophy, men have generally gone too far towards the dominant side and don't understand the virtues of the submissive side, so that's what they have to learn. Given what was happening in the world at the time-or today, for that matter-it's not hard to see how he got that impression.
My point in bringing up Byrne and Conway was that many writers have had issues that make Marston's pale in comparison.
As for Woody Allen, that whole story looks, as this community would say, squicky, but making a judgement like "the creepy old man of Hollywood" involves making a lot of assumptions about his personal life and I don't think either of us have that detailed a knowledge of it.
