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.
The problem with this world is that the intelligent people are full of doubts, and the stupid people are full of confidence.
