If Family guy is on adult swim then why do they censored family guy

[Cloud87]

I'm asking because both me and my dad love the show Family guy but however whenever it comes on adult swim then boom it's censored and no me and my dad don't know why is that i mean it comes on adult swim but they censored it and i don't know why would they do that here's my thoughts for them.

If they have a problem with family guy then don't show it on adult swim & if you don't have a problem with family guy then don't ever censored it when & if you show it on adult swim end of story and they need to stop censoreing family guy if they show it on adult swim if you don't know either that's OK i fully understand.
