I wouldn't really expect to find a discussion of Ft. Hood on a cooking/fly-fishing/model railroad/derek jeter website either.
I wouldn't put a discussion of Fort Hood in the tennis section,
but surely the non-tennis section of MTF was designed for tennis fans to discuss issues other than tennis. Which is exactly what I did.
You seem to be arguing that the non-tennis section should be removed and tennis fans interested in any other topic should go elsewhere.
So why do you even look at the threads there?
