Do we upvote or downvote if we think its a stupid question how does this work?

Theres no consensus on this.

Actually stupid questions, like ones intended to be offensive, or unanswerable debates like Apple vs android, do get downvoted.

If OP is genuine, or if the discussion is engaging, then upvote it.

I thought the community name refers to the answers in the comments, like OP asks something and doesn’t want to be asked stupid questions for asking such a thing.

No that’s not what it means.

Its from the phrase teachers like to say: there are no stupid questions.

The idea being, dont be embarrassed to ask a question others might see as stupid, because by learning the answer you will be less stupid, or something.

Ah that makes sense thx
