In fairness, this was more of a spoof that was canceled due to customer dissatisfaction and finding it to be in poor taste. It was also on a satellite network so neither subject to any public broadcasting guidelines or other OTA broadcast restrictions.

I could totally imagine a Monty Python sketch depicting Hitler in an absurd/comedic situation being rebroadcast on US public TV without issue. I think the previous comment was referring to a hypothetical pro-Nazi program.
