Rolling Coal: good or bad?S

Yesterday I read Flavien's post about diesel and saw most of the comments bring up big 'ol diesel trucks. So now I want to know how everyone feels about the thick black smoke that comes from modified light duty pick ups. Is it a sweet fuck you to Prius drivers or a shitty fuck you to our collective lungs? Is it bad on a bro truck but ok on a drag truck? Do you like performance diesels but hate black smoke? What does everyone think?
