> The onus should not be on the communicator to qualify every statement of opinion. This is tedious and unreasonable.

I fundamentally disagree with this. In my experience, it's in pretty much in possible for people to perfectly understand intent without a certain amount of effort from both the communicator to express it clearly and the listener to understand it. In practice, I don't think there's a good chance of successful communication for any nuanced topic without good-faith effort from both sides, and I can't differentiate between the language the author used and what I'd expect to hear from someone who reflexively dismisses any disagreement as in bad faith.
