Amen and hallelujah. Not sure why some folks seem to think that being "right," whatever that is, encourages exchange of ideas.
Two things. 1) Who the hell knows what is right? The golden age of tango was a long time ago. How can anyone alive now possibly know exactly how things were then? And 2) Even if we somehow magically knew what happened during the golden age, who's to say that that's the best or the only way to tango?
Yes. The hair splitting, quite frankly, is why I don't do AT. There's a milonga around the corner from where I work, every Friday night. It's close, it's accessible and it's cheap. But I have absolutely no desire to encounter the self-aggrandizement and inflexibility there that I sometimes see here. It's not about DF, though. Back in my early days in DF, I did a ton of research on other dance sites, including many AT sites. The, "I have the Holy Grail of Tango and you're a heretic" attitude is pervasive, IMHO. I've seen it in a lot of online AT communities. The irony is that the people who are so passionate about preserving tango in its pristine historical form can sometimes be the ones who prevent new, interested people from joining the community. At least in my case, I know that is true.
