I don't see Sasha as "fragile" or "brittle" it's just that compared to the other elite ladies her skating is less powerful. She skates with less speed, has smaller jumps, and has less powerful stroking.
I appreciate Sasha's line and positions, but what I love about figure skating is bold stroking and edging, speed, flow, secure movement and musicality and Sasha has none of these things. I find skaters like Julia Sebestyen or Joannie Rochette to be more talented and more enjoyable to watch than Sasha, does that make me blind and "disingenous"? I think it just means, like someone else said, "beauty is in the eye of the beholder." We can't all like the same things and agree on everything.
