We don't believe that emotional, illogical reaction is cause for inflicting harm via downvote/flagging option. Conversation is an option for resolution of differences, plus it allows the greater community to get involved which benefits all.
Thanks for sharing your experience @sethlinson. Disagreements are inevitable, but we appreciate the opportunity that Steemit provides to discuss them reasonably and openly. We don't disapprove of the downvote/flag option per se, but to exercise that power without even hinting at reason for censorship is absolutely dishonorable.
