...who will more than likely be the ones forming or changing opinions when there is a debate.
A very wise person who used to come here once said something along that line that while one person may be responding to a comment, there could be 100 people watching. So something I try to keep in mind when engaging in those kinds of threads.
Also, even though some of the debates might seem redundant to those who've been here for years, or like we're spinning our wheels, there are constantly new people in the audience, and more and more people waking up. So they are the beneficiaries...and proof that it's not all in vain.
