Live video chat is a good alternative, but I think more natural human empthay comes out in face to face experiences. People seem to understand the other side’s perspective more fully and confusions that can show up in email from things like poor word choice can be resolved quickly before they fester. Live video chat gets you much of this but isn’t quite as effective in my experience.
To me this observation just means that on remote teams you need to be observant of such issues and spend a little more time to resolve them, which can be a fine trade off for remote teams. (Or ideally avoid overly contentious debates in the first place)
