Saying there are white arts as well as dark ones is conceding the point, isn't it? One should be allowed to be persuasive as well as right, and sometimes just being right isn't enough, especially if the audience is judging the surface appeal of an argument (and maybe even accepting it or not!) prior to digging into it's meat. In such situations, attractive wrapping isn't just pretty, it's a prerequisite. So, I love your idea of inventing a protocol for DAtDA.
