Personally I think what she says is fair enough. She doesn't specifically say which "side" she agrees with, if either, but she feels quite strongly they should both be allowed their own views without being hounded.
I agree Radcliffe et al shouldn't have criticised JKR but I do think they are allowed to disagree with her and to say so publicly, and I think their views were genuine and strongly held. I don't think they were putting the boot in just for the sake of it.
I mean personally I agree with JKR but I think Radcliffe et al are entitled to say they disagree. It's the absolute hounding of JKR and the "no debate" that's terrible.
I think we're getting a lot closer to being able to debate the issue now, which is a great thing.
