I'll throw out another "class" of person - someone who believes something, and at least grasps the concept of philosophical reasoning enough that they'll attempt to build one of the basic forms of argument - usually an argument by analogy - and having done so, they'll trumpet their conclusion. Then, commenters will pile in, either being part of the class of people you mention (who will skip reading the argument and just check to make sure the conclusion is what they want) or being part of the same class who will review the argument, stamp a "lgtm!" on it, and upvote/concur. We're right! And look, it's got proof attached, too!
But then even the most amateur student of philosophy, perhaps about 60% of the way through their freshman (mandatory) Philosophy 101 course, would be able to examine the argument and identify mistakes so appallingly obvious that they might be provided as practice problems in their homework. The analogy isn't appropriate; or it begs the question; or it assumes some predicate where their proof may hold if the predicate is true, but the predicate itself must be proven for the conclusion to be substantive.
I see this a lot on reddit. Especially recently due to the abortion debates re-heating. Arguers - regardless of side - are so poorly equipped by our education system, and so poorly incentivized by the highly polarized/tribalistic nature of modern political discourse, that even when people try they're still not making any progress in reasoning about their positions.
