I get why people don't want to misgendered. But making up a new pronoun comes across as aggressive attention seeking.
A journalist writing about someone they've interviewed ... as part of doing the best they can for the people they serve, the readers, perhaps in some cases it's reasonable for them to ignore the preferences of the interviewee?
Through the article, this happens in various forms.
If the point of the article is to criticise someone's behaviour for being an "internet cool person"; opening by your opinion piece by stating you were too cool to bother to do something; and later stating that you as the writer are a normal person, and that you feel sick after infilitrating a group, there is a level of hypocrisy there.
I agree with you there are legitimate cases for ignoring someone's preferences to improve the quality of information imparted. However, the author doesnt state any apart from "didnt bother".
