Calling someone "daft" is a [WP:NPA|personal attack]] and "bullshit warnings" is likewise uncollegial, so I recommend that you calm down and redact yourself. I also reserve the right to leave appropriate templates on your talk page, as is required of me.
If you read WP:SPS, which I did, you'll find that it explicitly makes an exception for experts in the field, like Callahan. You also didn't deny that BLP is irrelevant.
I believe I've clearly shown that you are wrong on the basis of policy, so I'm asking you again to revert yourself and avoid sanctions.
