crankyoldman- look at Biglaw Lawyer’s thread; I’ve posted my employment history there.
I’m a Happy Alumnus of law school. I hated undergrad.
If Demosthenes turns out to be a graduate of a US News top-10 law school, with an employment history in Biglaw, then I’ll consider his or her posts as coming from someone who is intelligent and with experience in the area, and thus entitled to careful consideration. (I wouldn’t necessarily agree with them, since as well-educated lawyers, we don’t just blindly accept anyone’s view on anything.) Otherwise I’ll largely ignore them.
crankyoldman, you mention possibly being a barista. To turn your argument around: if this thread were about coffee, I’d certainly give your posts about coffee much more weight if you actually were a barista than if you were just someone who looked on the Internet about coffee and came up with arguments that you found. Same goes for Demosthenes’ posts: his or her background is certainly relevant.
For your other points: I think that you can figure out what mid-90s and “middle of the class” mean.
