Suit yourself. If that's the case I might as well contribute.
I'd like to know how people think Townsend isn't prog? If you've heard Infinity, that's one of the most progressiev albums ever. What else can go from heavy metal meets big band to a nice waltz to divine power to straight forward heavy metal to stoner Pink Floyd style to pop metal? And Terria...well, the songs are lengthy, progress greatly in feel (how about that breakdown in Deep Peace leading back into the main chorus?), all sound pretty different, use plenty of keyboards and textures to create atmosphere, contain varying emotions all throughout, use all sorts of different vocals...
If that's not prog, I don't know what is. Sure, Accellerated Evolution isn't really prog, and Ocean Machine is debatable, as is Synchestra (hardly though), but Terria and Infinity are prog.
Now if I told you Nile was prog...
