I'd guess most just want to dance, and are trying to resolve what they've been taught as AT and it's culture in their 'class' with what they find elsewhere, or multiple styles they find, or their perception of what AT is and should be.
I agree!
Even among devoted students and hardcore debaters of tango, the fraction who want to spend their limited time and energy asking, "What is tango?", "What is (what is tango)?", "What is (what is (what is tango))?", ad infinitum rather than dancing is too small to be relevant. So they settle for a construct and . . . so what? Why challenge that? Why shake it up and cause something fun to become a source of tension and philosophical self-examination?
For the overwhelming majority, going deeper than what they can see at classes, prácticas, and milongas, and hear from coaches, instructors, and teachers isn't necessary to be a better dancer, and in fact a total waste of time. If they
do have extra time to spare, it's better to devote it to physical workouts that train physical skills like strength, balance, and muscle engagement than to worrying about tango's framing and context. Indeed, worrying about social structure past "How do I get more dances?", musical structure beyond "Tango is in 4/4 and has a rhythm, implied beat, and melodies," or historical context crosses a line into wasted time if all you want to do is dance more often with Cherie, Emma, Marie, Nikki, and Sarah – or Chuck, Ernie, Max, Nick, and Sam – at that place at X Street and Y Avenue.
My description is silly for silly's sake, but it's still most likely a fair description of reality for just about all but a rarified subset of the tango community.
And I don't say this lightly. I take tango seriously. I just got back from a private salon where teachers and students of various levels meet to discuss and practice different perspectives on the dance, and to approach learning in a holistic, level- and syllabus-free way. But one of the teachers said something very true: "Don't overthink it. Your body is smart. Let it learn through doing. And when you go out to dance,
just dance." If you're thinking of something else but dancing, you're doing no favors to anyone, starting with yourself.
