Because some of us enjoy the feel of light bikes, experimenting with technology and material limits.
Others are attracted to a international forum that tends to show high end equipment, and then will purchase their way towards a light-weight setup.
However these same people tend to be the ones that do not account for fitness. Light bikes are not a replacement for good fitness.
Bike races are typically not uphill time trials. So the difference of a few seconds or 10 yards can be the difference between "being in the lead pack" and "dropped", which typically translates into an enormous difference in final time and placing.
So no one is claiming that a light bike makes up for poor fitness, but a light bike can contribute to a significant difference in performance.
I would suspect that nearly everyone who actually races would have had the experience of being only one or two bike lengths behind a group at a critical point in the race, yet just be unable to close that last gap no matter how hard you try. Since you are already as fit as you are going to be at that point, I would be delighted to have 1.5 kg less bike to have to accelerate.
Of course if you don't race, and just time trial up hills, you would never notice the small difference weight makes and it would be swamped out by a lot of other variables. So it could also be said that it DOESN'T make a significant difference to performance.

Indeed. I love the Team Sky "marginal differences" philosophy. It's what drives the philosophy of this forum. "Every gram counts".
But there's a difference between how a frame feels and what it actually does. For example a heavier, stiffer frame may feel like it's climbing faster, yet be slower. Perception is a very poor measure of actual speed.

It's around 4kgs heavier. I was terrible. Now I have my carbon bike, with some aero wheels and I'm flying.
Obviously it's the bike.
I had my doesn't fit me alu bike in the winter, as my lightweight steel bike wasn't ready, it's around 500g's lighter, and now i'm flying.
