Neither do I although some nonbinary people have commented elsewhere on this issue that while they might feel skeptical of this guy's claims and despise the violent crimes he committed, that not honoring his claim and preferred pronouns could be a slippery slope. Or, in other words, asking him to pass a kind of 'litmus test' could lead to other nonbinary people who have done nothing wrong whatsoever to have to 'prove' themselves. A little wordy there I know but that's kind of the gist of their objections.
