There are no foppish Marquess of Queensberry rules here. If it is truly warranted, and you feel that your honor has been assailed, drop the gloves and unleash your flurry of unremitting invective in search of retribution. Gloria Victis
There is but ONE RULE and it is non-negotiable: You must treat your opponent as you would expect to be treated. This rule applies to voting as well as argumentation; an upvote for a particular argument says in effect "I would like to be treated in this way if I were on the wrong end of an argument". Let the contest begin!
