This is a good time to point out that slippery slope is a fallacy.
Saying, "Experiencing some friction is good for building character" is not equivalent to saying "We should demolish all technology and force babies to survive on their own in the woods."
That the extreme position is wrong does not strictly imply that the moderate position is too.
There being a more extreme position that is wrong, doesn't mean that a supposedly moderate position isn't extreme. See: Overton window.
This is the particular problem with deciding a position, it's all shades of grey.
200 years ago a good number of humans thought that owning other humans was a-ok. Today that's mostly not true. In 200 years it's likely the vast majority of humanity will look at eating meat and owning pets at the same level of horror. Which is the extreme position? Which is the moderate?
