Because it's a beautiful thing. Not many people can hold an argument. I have very strong views on certain subjects. In fact, I've never actually fully expressed my views on this board, nobody knows some of my most strongest views, and I'm sure many here would never be able to defeat me on those.
You have already been defeated in this very thread by yourself. No one else is needed. Now it's time to pack your shovel into your bag and stop digging.
