i dont see it as mutually exclusive. you dont form opinions without questioning them. at least for me if i think something i have a lot of questions as to why im thinking this and if other people think that way or differently and ill look at many sides until i can come back top where i started or find i have an evolved or altered opinion.
questioning discussing analyzing disseminating... this is how real opinions are formed., until then its basically 'herd view', and you haven't really thought for yourself.
That's what a lot of people do for validation to debate or rant and they are not genuinely looking for advice. I actually answered a question today and noticed in the comments that the asker said she posted the question to find people that disagrees so she could block them.
