> White guys can afford to be color blind, because racism doesn't affect them personally. She doesn't have that luxury.
This has the natural implication that vast majority of white guys are color blind as a result. This assumption can generate a lot of unfounded biases, especially by those who are taught from a young age to perceive every white male as being oblivious to racial issues in their day-to-day lives.
It takes quite a bit of ignorance to be color blind in modern culture regardless of your race. Even without certain groups pushing for awareness at every opportunity.
Outside of maybe rural areas in North America and some parts of Europe it's hard not to be confronted with a wide variety of social interactions with other cultures - but even the bubble of rural areas are being broken down by technology as we all grow up with online identities.
How one confronts other cultures is a different issue than this inherent color blindness, racism is not necessarily a result of obliviousness or total ignorance but many times a result of some harmful - but willful - ideology.
Therefore, I believe it's appropriate to react with at least some skepticism when someone immediately shoehorns peoples races into conversations. Especially when their race would not otherwise have any influence on the subject at hand. In this case it was men talking about sex workers and porn stars, which certainly isn't unique to white men.
That said you shouldn't necessarily be dismissive of race in every topic, people's race has an important influence on their realities and I take issue when people try to pretend it has zero influence. My point is merely is that this should not be limited to just referencing white males, as it's unfair to act like this is a unique phenomenon for the majority of white male. Unless of course you're okay with basing opinions upon cultural stereotypes rather than the variety and shades of grey which make up reality.
The white males she references on the jet are very much the exception to the rule in any American city. This "frat boy" or "bro" culture is a problem that needs to be dealt with, and is a common problem in the finance world, but that doesn't mean it's a standard feature one should expect from white males generally. And most certainly not a basis from which to stereotype them.
Not to mention that sexism is as (or often more) prominent in many Latin American, Arab, and African cultures than you'd find in your average white american male. But even then stereotyping them as such merely based on their race, rather than their local cultures or subcultures, is fraught with risk. Would the men in these racial groups lack of 'color blindness' then make it more or less relevant to bring it up in such a conversation? Or is it only okay as long as it's 'white males'? See the logical issues here?
If she had said "white frat boys" I would have had no issue with the inclusion of race. Context and culture matters.
