Why do you say that? I think the main gist of the post was the OP thought it was an unsafe practice. By posting and encouraging some discussion, someone just starting out may learn a safer way of doing what is an everyday task on the table saw. I don't see it as a big deal, each of us will work to their own comfort level, but a beginner may save himself some grief, by preventing an accident.
If at first you don't succeed, try again. Then quit. There's no point in being a damn fool about it. W. C. Fields
