Ellipsis - // v_e, I can see your point ... if you consider Moslems to be "the enemy". //
I think the analogy is flawed.
1941 was seventy-five years ago - media, together with cultural attitudes, are a million miles away from where they were back then.
In that instance, I would entirely agree that using a Japanese presenter would be insensitive - based on very 'black and white' national views on colour and race - let's not forget that condoned racism in US states was a fact of life then, and not even questioned, much less resisted as it is now.
But this is 2016, and we have a sophisticated worldwide media presence, and hopefully, a far more sophisticated television audience who are perfectly capable of avoiding a backwards kneejerk reaction to seeing a Muslim reporting about an alleged Muslim atrocity.
To suggest that they require some level of 'sensitivity' about the person who presents the news to that audience is to patronise them, and lump them in with the 'looking to be offended' minority who make up Mr McKenzie's readership.
If instead you consider terrorists to be "the enemy" then, unless Fatima Manjia is a known terrorist or terrorist sympathiser, there's not a problem.
