This is probably one of the more stupid comments made on these boards. I like discussing college football. Specifically Clemson. South Carolina plays Clemson every year, our schools are in the same state. We often compete for that same players, etc? Is any of this making any sense to you?
Now I could turn it back around and ask an equally dumb question like, why is this board full of Clemson related posts? And we could go back an forth about the amount of time spent by each fan base on the other school and it would look completely similar to a thousand other posts about the same thing.
Let me bottom line it for you since the concept of the internet, message boards and being a fan of team has eluded you. There was a post about Clemson fans. As a response to that post there was a very sane, logical response about the cyclical nature of teams success. I agreed with the post because I believe this to be true. It did not cost me any money, it did not cost you any money. I did not actually walk into your house and demand you listen to me. This is the internet and guess what we are all here for the same reason.
I hope this answers your question.
