Because they’re trying to be accurate. What is wrong with simply trying to describe his position accurately for its own sake?
Author’s Note: I (David Solway) do not refer to myself using the pronouns “she” or “her”, but I am tolerant of those who use pronouns that differ from their biological gender, although such tolerance should not be made compulsory.
... Okay, so perhaps he should also add that note, just to be “accurate”, and the also guard against anyone making any wrong inferences about “him”, right?
Of course not, so the point is, you only stress the need for accuracy if there is some important distinction between a correct inference, and a wrong inference that someone might otherwise make.
And it’s my position that in the case cited from my original post, that no such important distinction exists, and to claim that it does merits the kind of inference that I made about that comment.
