Agreed. I'd like for flags to not be seen as an act of war :D
Especially for those that didn't realize they were stepping into such possible hostility.
Flags are just a way to disagree with the current assignment of the reward pool. Upvote is the other way to disagree with the current assignment of the reward pool. Adjusting that balance as you see fit is how steem was designed to work. Culturally, it evolved into something else.
