I agree only with your first two sentences. The situation that often occurs is a newbie with a 1-3 post history, uses a strange, confusing forum name, doesn't supply his location, and then typically posts a question involving us doing his homework assignment for him or wants help building some sort of anarchy device. It's very clear and obvious to us when newbie asks a genuine question, seems to have some basic knowledge to back it up and discuss it further, and shows evidence of doing some research on his own. Given that, I believe a good many of us would easily overlook his poor grasp of English.
