I suppose the difference is that Hawking wasn't, in himself, politically charged, nor was he voting on policies that directly impacted people's lives during the time of his Trek appearance.Meh. TNG did a direct drug PSA that would not be out of place elsewhere for the 80s
Trek bring on the nose doesn't strike me as out of step. If Hawking can be on TNG why not politicians, regardless of one's political affiliation?
Let's be honest - if SNW's next season had JD Vance (or, say, Nigel Farage) pop up as "The President of the Federation", our reactions here would range from bewildered laughter to total outrage, and rightly so. We'd be asking serious questions about what the producers' intent was, and if they intended it as an endorsement of his political platform.
There probably are some non-politicians you could get the same effect from - if Pike went to visit "a wise oracle" who turned out to be played by Joe Rogan, we'd again be thinking "what the fuck is this".
