Never mind that there is a pervasive cultural tendency to disregard a woman's accomplishments and focus solely on her looks.
And no, this has nothing whatsoever to do with "political correctness". This is simply being fair. You didn't have to mention appearance, or age. You could have just said, "There's quite a lot of women employed by the IT company I work for." But no, you had to slip in that extra dig about their appearance, and you then have the gall to claim that it isn't demeaning to those women to derail any discussion of their accomplishments for an attempted discussion about their looks instead.
