I agree, both generally and specifically. Supporting your argument is Bell Labs' `sexist`[0], a commmandline tool, part of the Writer's Workbench.
http://man.cat-v.org/unix_WWB/1/sexist
A relevant section from its man page:
[When given a file as input, sexist prints alternatives]
using neutral terms instead of sex-related terms.
For example "business executive" could easily replace
the stereotypic "businessman."
To me, "businessman"
can be gender neutral just as "guys"
can be gender neutral. Today we[1] don't use "businessman" for the same reason that in some years we won't use "guys"; it still gives a biased-towards-men picture of people.
[0] I'm citing Bell Labs because they're prestigious and respected by HN.
[1] Because I'm trying to influence the vox populi, I'm using "we" imprecisely. I hope that those who disagree with me follow my argument even though I'm not speaking for them.
