I thought
this was quite an interesting, and well-balanced, take on the whole farrago.
Where I agree with them is that there is no historical or social context to the (over) reaction to the tweet (which I actually thought was ill-thought, simplistic and trying hard to be a "sound bite"), I also think that everyone, whatever their race/religion/sexuality/etc has a responsibility not to be uttering xenophobic comments, especially those seen as role-models.
I also find it amusing that her comment appeared to homogenise one section of society, when the person she was tweeting with whole proposition was that that sort of approach wasn't appropriate for another section of society.
Was she stupid to say what she did - yes, imho.
Was there an over-reaction to it - also yes, imho (just like I think there is often an over-reaction in many areas of our society to many things, when we should be saying "was this person malicious or just being ill-advised/stupid").
