TenForward: Where Every Vulcan Knows Your Name

Janeway: would have had the filter off initially because she trusted her crew to exhibit perfect decorum even without it, immediately switched it on once the Maqui joined, then flipped it off again sometime later (specific ep recommendations anyone?) because she didn’t gaf anymore.

Sisko: considered turning it off but opted to leave it on to reduce bar brawls at Quark’s. Turned it off on the Defiant.

Picard: on, but removed “damn” from the censorship list, as a little treat.

Some Federation ships are in The Bad Place (equinox...cough).

You've been assigned to a ship in The Good Place.

Doesn't Commander T'Ana in Lower Decks swear constantly?

The Undiscovered what??!? Oh, there's a final "ry". The Undiscovered Country.

lol ... they turn off the swear filter and everyone starts talking like my trailer trash neighbours down the street

"Yeah, we fucking had a fuckin bbq last night, and I fuckin had a beer and the fuckin beer burst the fuck open and fucking sprayed fuckin beer like fucking all of the fuckin place and fucked up shit and then we ate some fuckin chicken and the fuckin chicken got fuckin burnt but we fucking ate it anyway ... yeah it was fucking crazy ... but how the fuck are you doing?"

It's all fun and games till they start swearing like quebecers

Actually I think this would be perfect middle ground for volcan profanity but it's based around logic instead of the catholic church

"Illogical" is just the translator making a mild version of the actual phrase "How the fuck did you manage to stay out of special fucking ed with a dumbass statement like that??"

Easy explanation: Upgrades to the universal translator have allowed more colorful language, which is often slang, to be translated correctly.

What was the first Star Trek show to include swearing? And have all since that one included it too?

The non-swearing wasn’t because they were more « advanced » in the series, it was censorship from TV diffusers at the time (in the 60’s). Swearing simply wasn’t allowed on TV.
