Guys and Gals,
I agree that debating creates in-groups, and to a certain extent that cant be helped. A lot of people who debate a lot are also friends. The important thing to remember is that the groups shift and change to include people new to the circuit, who begin to debate quite a bit. James Morris (to name someone from the top of my head) from Alleyns is just one of many new mates that i didnt know last year but whom i would certainly say is in the "group".
Plus debating isnt unique this this respect. Its pretty much similar in athletics, and other sports and past times.
Love to you all
