I tell them I have a - 'very low tolerance for anything verbal, whether directed at me, the opponents or amongst yourselves'.
Gives me a it of leeway when judging the spirit of the game and player-frustration with themselves.
Dissent is easy, dictionary definition:
dis·sent (d
-s
nt
)
intr.v. dis·sent·ed,
dis·sent·ing,
dis·sents
1. To differ in opinion or feeling; disagree.
2. To withhold assent or approval.
n.
1. Difference of opinion or feeling; disagreement.
2. The refusal to conform to the authority or doctrine of an established church; nonconformity.
3. Law A justice's refusal to concur with the opinion of a majority, as on a higher court. Also called
dissenting opinion.
Basically, if you disagree with a decision of mine, it is dissent. So there has to be some kind of tolerance or you would end up carding everyone: "Aw come on ref! What was that for?" or "How does that work ref?" while showing disagreement are unworthy of a card, unless it's the same player all the time. Angry or snarly dissent is different.
We have a code for cautions "Unsporting remarks or gestures" that I use quite often, when many may put 'dissent' down.
Starting with a 'Low Tolerance' gives me the first 10-20 where I can use a quiet, or stern word to get on top of it, and if I've done it properly, from then on it's rarely a problem.
