Re: To which you can add ...
"I'm a white, straight, over-40 male."
Then you've had 30+ years benefiting from the racism and sexism that pervades society and our industry. It's probable that for some of the jobs you (and I) have had there were better qualified/experienced women or non-white people available, but they were screened out by a society, education and work culture that was (and still, mostly, is) sexist and racist. At least there's something positive behind the affirmative action that might be holding you back as opposed to having your UCCA form or CV chucked in the bin just because you were black and/or female.
