Thats what I hate too tho, when people are disrespectful, my rule of thumb is unless they have done something to lose respect from me, is to treat them with respect. Then other people have even more respect then those people from me, for instance, if I'm racing one of the higher respect people, I'll usually battle them that much harder, but if its a normal person, just race normal, and be sure to not do something stupid. Finally, if its a person that has completely lost all respect from me, I'll usually block til the cows come home, and get him frustrated.
