This was possibly the most offensive episode from TNG.
I have pushed back hard on the idea that the Ferengi are space Jews (the Bajorans are space Jews, the Cardassians are space Nazis). The Ferengi are space capitalist Americans - Riker even called them “yankee traders.”
I’ve defended, somewhat, the sexist aspects of TOS by saying it was the 60s and they were trying. They probably did more good than bad.
I know that LGBT-phobia (or concerns about it) made them back off on how Garak was played. I know the Troi stuff ranged from cringe to rape culture, and I know that having Riker being neo-Kirk with the ladies was… a choice.
But the Irish episode was the closest thing to blackface I’ve seen on Trek. I can’t even watch that episode.
