I'm probably not going very far out on a limb by guessing that you don't own CCO. If you did you'd hopefully know the difference between what you've invested in and the Clear Channel Radio unit. To be fair, Clear Channel didn't call anyone anything (much less Clear Channel Outdoor Holdings).
Rush Limbaugh is a complete douche to be sure. I'd never defend him nor own a company that packages him for market. That being said I've been building a small CCO position since about Thanksgiving and I've done really well with it. So I will happily take the other side of whatever protest sale you opt to make on CCO.
If you're not about the money, I respectfully suggest you're on the wrong message board.
Ps. My long term sentiment that is probably stronger than hold but not quite buy. Call me an accumulator. :-)
