Honestly, you've put way more thought into it than I have. The fact they don't have it on their official account would imply they might agree with you, however.
I'll admit that being of an age (Gen X) straddling both generations, might make me more tolerant and willing to let such stuff go than the younger generations of today probably would. I tend to remember the skit probably a bit too fondly because my older brother loves Monty Python and this was one of the many skits he could recite by heart. I, of course, looked up to him as a kid {5 years my senior), and had no clue about what those words meant until a few decades later when I finally stumbled upon a discussion of the skit on the Internet.
My apologies if that's still too offensive for your tastes. I can understand that, even if I don't personally feel it. If it were something they were still promoting today, then I'd probably feel a lot less comfortable with it myself.
