It's certainly worth talking about and fixing--the difference between segmentation and discrimination. Like in the HUD case mentioned in the article, discriminating based on age, gender, race, etc. are actually illegal. Not every industry is as regulated nor are they all at risk of it because of this.
To me, there's not a question of "should we make this better?" because we're talking about basic rights: the right to not be discriminated in the pursuit of a roof over your head or a job to pay you a living wage (housing and employment). IMO, a very different question when you advertise anything outside of those basic rights. Plenty of grey area to talk about there.
If I’m advertising a $20M luxury penthouse overlooking Central Park, am I permitted to advertise only in the WSJ and Robb Report (or whatever rich people read)?
Does that change if I learn those publications skew overwhelmingly male?
