The Usurper:  You're wrong.  They are both insulting and ad hominem.  Whenever you argue "to the man" that's an ad hominem.  Saying one's brain is under the influence of Fox is another way of saying one doesn't think for  him or herself.  You didn't address the issues,  addressed the person. 

And perhaps you can explain to everyone here how the first insult is "strictly accurate."  How can you possibly know?  To whom are you addressing this insult (since you seem to be generalizing it to all repubs)?  You can't have your cake and eat it too Greg.  Ad hominem is to the man.  That is what you did in both cases.  Man up.
