Actually i've seen more bad arguments from the people who want fixed fairing, all summarized in: "Hey p-fairings aren't realistic"-> Why the problem of "realistic" didn't came out with FAR/Stock aero discussion? "Hey it's more fun to have restriction" -> Well, it will be more fun if you have folding parts, but we don't have one. Anyway nobody is forcing you to make *crazypayloadof34mt*, you can simply make realistic payload which fit in a "realistic" fairing (as i do using p-fairings).
