First of all, any thread which needs to be posted under a psuedonym is surely childish. If one cannot post something under their real name, then dont post. The only exceptions to this are Shivas and John Kavanaugh.
Nonetheless, carts are amazing. Consider this: without carts disabled people, and a lot of older people could not play the game. Also, what happens when a member has 45 minutes of daylight left after a long day at work and wants to fly around for a quick nine - a cart is a great option.
In any case, my favorite rounds ever have involved the use of a cart. Some four years ago I played the last rounds of golf with my Dad the he would ever play. Due to his disability, he could not play without a golf cart. I will forever cherish those rounds, which would not have happened without a cart. In fact, the last round I played with my Dad was with a fellow GCA'er, who also used a cart. We enjoyed our day very much.
This past year, my high school team was defending a title which we had won the year before, for the first time in our school's history. I started out horribly, with a 42 on the front. I walked to the tenth tee in an admittedly bad mood, only to see my Dad and my Mom sitting in a cart, ready to watch me play. My Dad had not seen me play since our last round together - the fact he was able to make it was special and amazing enough as it was. I went out to shoot a -3 33 on the back. That was the only tournament my Dad has ever been able to watch me play in. I know I made him proud, and I was surely the happiest person alive that day. He would not have been able to attend without a cart.
So sure, point out that golf was not invented with carts. It was also not invented with titanium drivers, sharply grooved wedges (or wedges in general), modern putters, containment mounding, etc etc. Those things are all prevalent today. Of course, so are cars, televisions, airplanes, shopping malls, and lots of other things not around when golf was invented. To acknowledge the use of golf carts as a fault of the game and a way to less enjoy a round - well, you are very wrong. Open your eyes.
