Are you arguing that we should share our degrees, grades, upload a CV with a picture (maybe I'm more believable when we're talking about white middle-class people if I prove that I'm white a middle-class guy)? A driving license showing that I'm allowed to drive trucks of all sizes, for the off-chance that I'm making comments on stories relating to that? Your idea starts out simple and innocent, unless you think it through. You are not entitled to know these things. If people argue about math and you cannot judge who's right: Bad luck. That's not a reason for them to prove anything to you. If you actually care about math topics and notice that usually X is supported by most people or - after investing some time of your own - is right according to your own investigation, X gains your trust. Y, always arguing against X, is probably talking bull.. It's the same in real life. If you meet a guy in a bar and you start talking about something other than weather and nonsense, how do you judge him? Unless you're way out of line you probably need to learn if he's talking sense or regularly pulls things out of his rear end as well. Do the same here.
