Right; and in communities where bad intentions are not the norm, usually there's some sort of moderation/escalation path/group of people you can go to for a second opinion, to ask "am I misreading this, or is this person being unnecessarily combative/abusive/whatever?". Those people can then look at it from a neutral point of view and tell the other person "hey, knock it off/tone it down a bit/whatever", which is usually all you need if it is a "just having a bad day" scenario. Or if there's a developing pattern of bad behaviour they can take further measures.
