I have no problem with Icahn the man. I don't trust Icahn the businessman. I don't hear people speak of their love for him or his generosity bespeaking his fine character.
The more I earn, the more I give to my charities of choice. My friends are the same way. They and I know this about ourselves.
Icahn is such a high profile guy, I'd expect to see his generosity blasted across the Internet but I've not seen it. However, I won't indict him as I may be missing information.
So all I can say with certainty is not that I dislike him, but that I feel no love for him.
