that's more like being conditional that we cooperate. If my enemy would say that I could find it offensive and it doesn'ty compel me to change my actions. If you try to use utlitarian theory to (en)force a cooperation the argument doesn't go throught.
As per a recent comment this thread is meant to voice contrarian opinions, that is anything this community tends not to agree with. Thus I ask you to post your contrarian views and upvote anything you do not agree with based on personal beliefs. Spam and trolling still needs to be downvoted.
