Because he is a man of ZERO MORALITY and is a master of "trash humor"; the guy is utterly classless and a disgusting degenerate
Sure he is mega talented , no doubt, but why cant he inject less crudeness and vulgarity into his shows.
Also the guy has to constantly interject his far left wing radical views in so many shows that I quit watching it years ago.
Seth is rich and popular but a pretty low life guy

Butthurt internet idiots.

Butthurt internet retards.

He loves to insult almost everyone in this boring world which I find him interesting and clever.

He's very mean and self centered.

Because its popular to hate him, the same idiots who claim hes horrible and family guy and american dad sucks in the same breath will jizz all over absolute embarrassing garbage like bobs burgers (id like to see everyone involved in that show except for Jon benjamin take a nosedive off a cliff its so off putting) and say thats what smart witty comedy is all about. They all tip their fedoras and suck each other off on message boards saying how much they hate him yet I bet in secret they actually do watch his shows. I'm a huge fan of family guy and american dad but I'll be the first to admit I don't like his movies really at all but his shows are probably the funniest on tv.

Good news, no one in this thread is talking about Seth MacFarlane except you!

Personally, I don't like people talking S about Seth MacFarlane.
Brony who is also a Metallica and Iron Maiden fan.

Isn't he the guy who created Spawn?

This message has been deleted.

He did write it for a while.

Oh idk who Seth McFaralane is never heard of him

That's true, the opening credits do mention that about Seth MacFarlane.
The OP is talking about Seth McFarlane though. And as I stated, Seth McFarlane has nothing to do with the show. You for some reason seem to think that he does as well.

The first name to appear in the opening credits of literally every episode is "Executive Producer: Seth MacFarlane"

Prove it!

He doesn't write the show but he produces it

HE'S A PHONY! A BIG FAT PHONY!

You really think Seth McFarlane did that?
When I tried to look that information up, it didn't say anything about him creating, producing or staring in the show. Please let me know where you found this information.

Lol, he created, executive produces, and stars in this show

Hate Seth McFarlane I've read that people just can't stand the guy
Who is Seth McFarlane? Why don't you ask him directly why people hate him so much?
Furthermore, why are you bringing him up on the Family Guy board? He has nothing to do with this show.

The parents television council also hates him too because of the show's infamous history of controversy. Even overly sensitive critics on the Internet despises him over little stuff.

I don't hate him, matter of fact I'm a die hard fan of Seth and I think it's unfair he gets all this hate. I think most of his haters are South Park fantards who only hate him because Trey & Matt hate him(for no reason)
