I'm not really talking about teaching and guiding though.

If you look at the meme, one of the responses is something like "PRs welcome."

I think that's appropriate in certain circumstances.

You are correct, there is nothing wrong with a lack of knowledge or dumb questions. I'm referring more to how they ask their dumb questions.

Some newbies come with hostility, pride, and entitlement, not ignorance.

They request new features, say something sucks bc of blah blah blah, and then get mad at people responding rudely back. But what else should we respond with in this kind of situation? They aren't looking to learn. They are looking to degrade projects, users, and maintainers.

They aren't looking for answers; they're looking to be mad about something and confirm their opinion that "Linux sucks" or some other such bias.

So yeah, when someone comes humbly even with bad assumptions, absolutely correct and guide, but there's no point guiding people who don't actually want guidance, ya know? Pearls before swine

So sometimes these aren't bad responses
