I'm arguing that "Python is easier" is false, simple as that.
- Beyond toy examples, writing Python isn't easier. Writing reliable, easy to maintain, bug-free Python programs is just as difficult, and your average person won't be able to do it right off the bat.
- You don't need to really know what a monad is in order to write Haskell as a beginner; that's a red herring.
If you want to argue that it's easier to write toy examples in Python, without regard for good programming practices, then... it'd still be debatable: if I remember correctly, some years ago there was a post here about someone teaching Haskell to highschoolers, to great success. They found it fun and easy.
