> Only if you think that "diversity" is somehow abnormal.
I don't, and you chose the value-laden term "abnormal" instead of "demographically atypical". Convenient that you chose the term that I would never use and that makes your argument look less preposterous.
> Why is it a calculated move for companies like Google, whose CEO has brown skin, to have some of their advertisements include brown skinned people?
This implies that brown skin is an indicator of diversity. To use your method of reductio: ...only if you think that diversity is determined by superficial attributes like skin color.
> The real cynical move would be to make them all white to appease middle America.
You one-percenters in the Bay Area must be very insulated; appealing to "diversity" does appease middle America. You could never get away with all white characters now, and I'm sure you know that.
> Why do you feel the rest of us have to hide our existence to appease you?
False attribution.
