Re: There is no place for discrimination on Facebook
For all Facebook's faults, however, this isn't a new phenomenon. Employers have always targeted advertisements - knowingly or unknowingly - by the choice of publication in which those advertisements were placed.
You're right, there is a comparison to be made with placing a job advert in a magazine with a known strong demographic. You may advertise for a builder in a DIY magazine, knowing full well that most of the people reading it are going to be men.
The difference is that a woman who is looking for a job as a builder does have the option to buy the magazine. She may be in a minority, but she can still access the job advert if that's what she wants. On Facebook, the adverts were explicitly only sent to men, and the woman looking for that job would never have had the opportunity to see it.
That's why this is being claimed as sexist where other forms of demographic targetting are not.
