fwiw (maybe nothing) I know what you mean about finding certain job postings off-putting. For myself, I don't think it has as much to do with the job posting itself as much as it may have to do with how I am feeling about myself at the moment, and how much I hate the rest of the world.
I can understand and won't argue about your being a woman and being put off by "the guy" language. I'd probably feel the same way, if only because I am 50 and "the guy" seems very young.
