I just reread all 25 posts. I don't see a single instance of anyone even implying that a heavy rider isn't "deserving" of a light bike. The closest anyone comes is this,
"If you are in anyway over weight, concentrate on losing body weight. It will pay all sorts of dividends. Than, when you reach your target weight, reward yourself with a lighter bike."
And, that looks like a very honest and direct response to the OP's question.
If performance is your concern and you have a functional, bike suitable for the rides you're doing, it makes a greater difference to focus on improving the motor/engine of the bike that comprises 90% of the performance equation then worry about the bike.
