Earlier quoted context omitted.
I was under the impression that the only way to use "broad" non-pejoratively is in reference to the actual breadth of something. That being said, sometimes it's safer to study abroad from afar.
Yes, you can't say it any more... It actually fell out of favor long ago, but originally it wasn't considered all that bad of a term IIRC (I was pretty young).
alexophile: you may be correct about this- I'm too young to remember. But I heard it used by people who had no other signs of misogyny that I ever noticed, which is why I had that impression. Carlin was one of those people to the best of my knowledge.
steveklabnik: But there are terms that you "can't use" now that were never perjorative. The scientific name for the race to which African-Americans belong is "Negro." Sometime in the '60s (I think) the leaders of this ethnic group took offense at the term. So, you can't say that somebody who used the term in, say, the '50s, was necessarily using it perjoratively (although you could make the argument that somebody using it non-scientifically in the '80s may have been).
