Depends where you are, and who says it. A nobody can say it and get away with it, particularly in more liberal parts of the country.
If someone prominent says it, especially a celebrity or a politician, they would get tarred and feathered in the news media and the constant faux outrage machine. A small segment might point out that his points are valid, but they would get overwhelmed by people whose jingoism has been singed by the comment.
Anyone who doubts this should see how any celebrity who offered any criticism to Us policy during the Bush years was treated by national media. Right wing tv, talk media, etc would crucify them, most other places would "report the controversy" and have bullshit non-stories about people being upset by the remarks without taking a position or bothering to note any facts, while a few places like the NPRs of the world would analyze both the facts and media response and likely give unspoken, tacit approval. MSNBC and liberal websites would be fully in favor of it, and probably say a few dumb, overreaching things along the way.
As for the show itself, I think the first episode showed both promise and flaws, and it'll be worth checking out a few more to get a better feel for it.
