I work in communication (I develop marketing and advertising strategies) and I have always had a chip on my shoulder when it comes to language use - not just in terms of what the communicator means, but more importantly, what the audience hears.
To be honest, I don't even like the term "feminist" because it automatically divides people into camps, based on something outside of their control, before any conversation can even start to take place. The reason I went into detail on your examples is because I wanted to highlight one major distinction between discussions of sex-equality and discussions of race-equality. I understood the gist you were trying to communicate, but the examples you used illustrated that you did not.
Equating the two is dangerous. Your examples, for instance, are not what I would call examples of privilege because they are based on real-life, factual differences in capabilities between the sexes - they come with drawbacks. No such stark differences exist between black, white or brown.
Distinctions between men and women can be divided into (A) biological reality; or (B) social construct (which may be informed/necessitated by biological reality, and may be temporary).
Distinctions between black and white are almost exclusively social and based in circumstance. As far as I can tell, they are not at all informed by biological reality, and so they should be temporary.
Point to specifics. For example, as a result of racist policies no longer actively in enforcement, do the railways still not pass through nearby certain poor predominantly black areas, making it harder for them to aspire beyond their circumstances? Push for expanded public transport into economically struggling districts - don't tell me "whites get trains".
Anyway, I don't think we disagree that strongly. I just go through phases of verbosity.
