Have you seen the episode in question?
The girl dating the family guy's son has Down Syndrome and says her mother was the former governor of Alaska. Furthermore, there is an entire song about dating a girl with Down Syndrome, with references to being a whore as well as other unseemly things.
But why don't you just watch them for yourself?
Mocking people who have disabilities or other health conditions isn't funny. These jerks will never malign the children of Democrats, but only the children of conservatives and Republicans. Everyone watching the show knows these jokes are making fun of Sarah's son, Trig.
i’ve seen the “making fun of Trig” clip, and it doesn’t make fun of Trig. I haven’t seen the other clip, and I don’t watch Family Guy, but people who do have described the entire show in this thread, and the description doesn’t match the rhetoric of “attacking Trig”. Unless Trig is a teenage female.
