i think it all feels very awkward a lot of the time because... it is. it's not in any way organic, authentic, or deeply felt, it's simply being done for the sake of doing it, & it shows. that's what's weird about it - how ludicrously intrusive & obviously 'stuck in' it is. back in the '60's, tv series, like star trek & perry mason, began incorporating black actors, & while it wasn't always perfectly smooth, it was almost uniformly done in a far more low-key & less awkward way than is being done now. the way it's now done feels much more like you're having certain 'things' you've maybe had thoughts regarding being 'clarified' for you, in a sort of gentle (but explicit), sesame street manner...
so, yeah: if it also all feels a bit condescending a lot of the time, it's because... it is... it's being encouraged by individuals who feel they 'understand' something that the vast majority of the rest of us do not, & are therefore in need of their enlightened guidance. because, if this wasn't so, how, exactly, would these individuals go about earning a living? i mean, surely not by actually working?...
