I don't think it's fear. I've eaten quite a few pizzas over the years, and potato pizza aside from the double starch, just sounds incredibly bland. Pizza is a guilty pleasure for me, and I won't waste the calories on blandness. Case in point, I will not ever eat a plain cheese pizza, regardless of the type(s) of cheese. Oh I've tried, but never again unless I was starving. What sounds incredible is Corky's pastrami pizza which I still have not seen on any menu. It will happen.
