> it’s hard not to notice a certain similarity among them, chiefly in skin tone (pinkish), hair colour (grey to white) and chromosomal composition

And its hard not to notice a certain dismissive, condescending tone here, isn't it?

Never mind that they might have been individuals with very different opinions about things and different levels of achievements that (perhaps) ought to be respected. 

Forget all that stuff. since it isn't relevant. We can be very condescending of them since they belong to 'the other'.
