I freely acknowledge my biases:
I think that operating systems should work well out-of-the-box for consumer users. I think that is a minimum requirement for any desktop environment marketed to consumer users.
I think that too many Linux enthusiasts miss the forest for the trees, so consumed with the power and customization possibilities of Linux on the desktop that they forget that Linux on the desktop is not going to grow market share unless and until Linux is suitable for use by consumer users who want an operating system that works well out-of-the-box without customization beyond the basics.
You suggest that users who want an operating system that works well out-of-the-box, beyond changing backgrounds, working through the settings menus, and adding/removing applications through a GUI interface, and neither have nor want the level of knowledge needed to go beyond that are "lazy", "unwilling to learn" and "ignorant'. Your statement encapsulates the attitude of too many Linux enthusiasts, and it is exactly a case of "looking down our long noses are users who aren't."
So, "How to address the notion ...?"
A good place to start might be to accept consumer users as they are and meet them where they are -- users who expect Linux to "just work" in the way that Windows, MacOS, Android and iOS "just work" -- and rid ourselves (as best we can) of the notion consumer users who have no interest in joining the Linux culture are "lazy", "unwilling to learn" and "ignorant".
I realize that my view that Linux on the desktop should work well enough out-of-the-box to meet the needs of consumer users who don't want to develop Linux skills is about as popular in the Linux community as dog droppings on a hot day, but I don't think that Linux desktop will grow market share until at "beginner" distos are good enough to do just that.
