No, you !@#$ing ass hat. I don't have a problem with anyone making fun of politicians, lord knows virtually all of them deserve everything they get and then some. The argument, which you state that you understand, isn't about whether Sarah Palin deserves to be made fun of.
If you equate Mock picking on someone on a message board equally to Seth McFarlane using a Down's kid to make fun of Sarah Palin, then you're an absolute moron (which is something you should take personally, not the ridiculous idea that I think politicians are better !@#$ing people - that's one of the dumbest things ever tossed at me and I regularly converse with Steely, Conner, and pbills. That means you're moving into dark territory).
"Family Guy" is generally very lazy. This is a perfect example of that. There were a million ways they could have made fun of Palin. Using a Down's kid isn't one that's acceptable.
