is there a difference between enjoying the art of playful flirting/courting and PUA?

Not asking if it's merely possible to court/flirt without being toxic (because of course there is, absolutely, I agree). I pose the question the way I have because I have yet to be wholly convinced that PUA is inherently toxic, and we aren't allowing the manifestation of bad actors to paint a view of enjoying the transactional nature of flirting to the point of finding ways to make it more engaging than simply engaging in small-talk/banter/exchanging statements back and forth at each other about life, the universe and etcetera-and subsequently-wanting to find ways of improving how you go about courting relationships.

tl;dr - "hate the player, not the game", etc.
