I had to continue on a sep sheet :)
if the person who says they were offended was truly offended then it behoved them to say so at the time ( as i have been known to do on one or two occasions :) ) or to make an offical complaint.
Racisim or any other form of prejudice is not nor ever should be acceptable and the fact that this is just a chat room is not an excuse. However, if the person concerned was truly offended then they should have said so and not made a point of singling out one particular chatter and making it an issue in here.
if they feel that racism needs to be dealt with, then deal with it.
