It's very simple Frank, it's all in the tone of how you put the jokes out there.
You see, you have to put the jokes out there in such a way that the Liberal's don't have to guess that they are being picked on, you see if they know that they are being picked on they can understand that but when they have to guess or scratch their heads and wonder if they are being picked on that is why they call it hostile because you are making them think and you know that is difficult for them with limited IQ.
So be bold and proud and put those insults to the liberals in uppercase bold lettering to let them know how much that they are disliked. LOL

And don't forget the excess punctuation and obscenities!

I think I understand why this is happening. Liberals believe that Bush is bad, and that they should not like him. I am smrt.

The audience didn't laugh at Colbert because they thought he was talking seriously.

Frank,

Illegitimi Non Carborundum

Always know that you are on target when the moonbats are frothing. It is when the moonbats are laughing that you know it is time for rehab.

The moonbats simpy cannot accept auything humorous at their expense. The main difference between th eLeft and Right is that the Right will even laugh at themselves when something is "over the top". Nothing about the Left can be considered (by them) as being "over the top".

I think this is more along the lines of how they crucify people in the media. "It's the seriousness of the charge, not the nature of the evidence." They feel the same way about comedy. It's the subject of the joke, not how funny it is.
