So we aren't allowed to learn from other cultures? Political correctness gone to far?

Political correctness going too far? Free Ottawa yoga classes scrapped over fears that the teachings could be seen as a form of "cultural appropriation."

Isn't part of respecting another culture the realization that we can learn from that culture? How can American (or in this case Canadian) society value and learn from the cultures of India if we are afraid to do anything, like yoga, for fear of not getting it perfect? If we are told we shouldn't practice anything from outside our own culture because we will never really know what being in that culture is like, then we will never learn from other cultures. How can we respect other cultures if we are afraid to learn from them because our learning isn't totally authentic or perfect?

I think it's a case of the perfect being an enemy of the good.
