What are some of you talking about???
Offering a draw is not rude. Neither is rejecting said offer.
How is it rude to offer a draw when you're in a losing position??? I don't follow the logic. The worst that can happen is the opponent says 'no'.
If you take offense when someone offers you a draw and you are clearly winning, the problem is with you - not with the opponent. There is no insult inherent in a draw offer. Simply decline the offer and play on. No need to take offense to it.
It's unfortunate that some chess players are way too sensitive these days...
once i declined a draw to an eye patched man and he tried to hook my temple. luckily he was standing and FIDE disqualified him ON THE SPOT!!!!!
