If you've seen Juan by himself on any other FNC show, or read some of his writings, he really isn't that bad or state positions way out there. And I think in so-called "real life" he is a decent guy.
Juan just has a bad habit sometimes on 'FN Sunday' of parroting the left's inane and irrelevant talking points (DBM and Beltway version) and gets slapped (appropriately) upside his head by Brit.
I agree about Juan and sometimes I wonder if the producer/editor asked him to behave how he does on the panel just to get the others going and give added interest to the viewing public.
Maybe thats his job there, poor guy. After the show he and Brit probably go have an expensive meal somewhere neither of us could afford, LOL!
