I see both points here... i haven't watched sorry.. (yes, if I am commenting without watching, perhaps this thread should get into the politics section of the forum)
Some say : art is art... others say : art shouldn't be about such topics...
Here's what I can contribute to this thread.
Cultural appropriation is a rather new concept.
For those who don't know it's when people from another culture, take on a topic, discussing it or transliterating it into art (movies, dance, anything) from a foreign culture to theirs... In general, it's not a good move as the world is finally realizing (and still has a lot to do in that sense) how badly everyone has treated other humans from other cultures.... there are so many fine lines NOT TO CROSS when it comes to cultural appropriation... that's it's a real mine field. An artist or a performer should be aware of this and if they are willing to use such content, should do due diligence and consult, research and try to understand the deep roots of a culture. Most of the times though, it's done very casually and it is quite insulting to this movement that aims to show respect to cultures that are/were oppressed.
For instance: D/S doing a "native" dance for Vancouver 2010... considering the history of British Columbia, and Vancouver, it was a very inappropriate move... It could have been perceived better if they had worked with local tribes, if they had contacted any expert in the field... but no.. it was so tacky that people were struck by an awkward silence. We could bring up a bunch of other teams doing bollywood or having jewish/holocaust themes... It has happened so many times....
However : there are multiple fine lines... sometimes, a performance CAN bring people together, whatever the past. Julia's Schindler's list is an example of that. Sometimes art or performance can bridge the gap between cultures. Sometimes though, it is seen as appropriation.... in other words : why would anyone take the culture of an oppressed people to earn profit out of it... to entertain... ????
I understand Averbukh is Russian-Jewish... however his track record is just ill here.. with the oh so many programs with controversial topics he has conceived...
On top of that, he doesn't need to defend them as he is not the one performing them. To me, it appears as he seeks those topics in disguise of lack of true artistic inspiration. It may be a harsh judgment but that's what his track records imply IMHO.
