and so, if you go by silicon valley populations, the stereotypical 'white guy' almost does not exist anymore. walk the bay area streets and you find mostly asians, and they don't have the same feeling about what made america great compared to someone who was born and raised here.
One of the main assumptions underlying this whole post is distilled in these couple of sentences. I submit it isn't possible to know the feelings of someone from just looking at them. Moreover, the silicon valley and surrounding areas have been racially and culturally diverse for many generations, so neither can you tell from looking at someone where they were born and raised.
Blaming the complacency of the voting public on immigrants is pretty silly, in my opinion. I'd say your 'average' person (white guy or otherwise) is disengaged from politics. When I look at how politics go in the US, I'm certainly discouraged from being engaged by the undue influence of money, our goofball first-past-the-post elections, and blatant gerrymandering. I don't think we can blame any of those things on immigrants from Asia.
