I like the overall positivity of the show, and also I actually enjoy Seth Macfarlane's formula. American Dad is my favorite overall, with Family Guy second, and this show last. Also, it isn't a homoerotic thing between Stewie and Brian (even though Stewie is often portrayed as homosexual or at least bi sexual) it is more a friendship between a boy and his dog. If you are taking cartoons that seriously that it has to inspire you or something, then you have completely missed the point of a cartoon, which is just to have fun and be funny. So relax, it doesn't have to be another South Park to be funny.
Sometimes you gotta get over racism and take
I personally as a minority think if there was no racism
television would be nothing
Racial Jokes make things funnier
I mean it's just words
So just take don't worry about
because at the end of the day
Racism is immortal and will never leave
you just have to learn to laugh at it
and not take it personal
because you are just gonna make yourself mad
