well, there is a different between a) not liking someone and b) posting accusations about someone and not presenting whatever evidence you believe will support those accusations.
and, in my opinion, when challenged to physically prove their point and coming back w/ a very weak comeback doesnt do anything to support the original accusations.
and, in my opinion, responding w/ the man up argument doesnt do anything but muddy the waters. [an aside - do any of you guys ever tell your buds to "man up"?? i've only ever heard it from women. interesting.....]
tho, there are other alternatives.
mercianna, you could arrange to me several people at a place of your mutual agreement.
and then have them "witness" about you.
or, like johnny said, just ignore him, dont let him get to you, and move on.
i saw a great bumper sticker today.
DONT HATE THE HATERS.
IF YOU DO, THEN THEY HAVE WON.
sounds similar to
.. what Yoda said about the dark side in the 2nd star wars [episode 5?]

.. "know your friends and know your enemies even more."
.. "make love not war".
.. and "love your enemies to death"
peace be with you all!
