As I said, if you want STRICT to complain about inconsistencies in case or even to make every instance of an identifier consistent automatically (so if you declare thisVariable and then refer to thisvariable, the second will become like the first), I agree. But case sensitivity is dumb, and you haven't managed a single coherent argument in its favor.
Look, we're past this now, alright? If I have to explain why case sensivity in a language is a good thing, I'm obviously talking to someone who won't understand. There's a reason why all the heavy hitter languages enforce case (Java, C++, C#, etc).
