and frowns on those that might involve discussionNo, it explicitly forbids questions that involve discussion.
The point of Stack Overflow is (and to a large extent always was) to be the place for definitive answers (and their alternatives) to well-asked questions. It is not a place for discussions, ranked opinions, interesting conversations, or anything else that does not have a "right" or "best-guess" answer.
It so happens that many questions are interesting to the community of people who visit Stack Overflow, but that doesn't mean they are contextually appropriate. If you want a discussion, go elsewhere. This isn't just a "if you don't like it, leave" judgement: it's explicit in the design and mission of the site[1]. There are better places to discuss things, just not on Stack Overflow.
