Answer:
A lot of radio has turned into such garbage in recent years that it happens
every day. Of course, it's gonna make you sound like worse crap than the
person you're putting down, and it makes the radio station sound like trash,
but if you have some kind of a driving need to run yourself and everybody else
down in public, then there's sure to be a station near you where you can get
away with it.
On the other hand, if you're asking because you heard somebody else do it, if
I heard it on one of the stations I listen to, I'd complain to the station's managers,
and especially to their advertisers.
