(a) the conduct in my original post (above) that led to the indefinite ban.
(b) the history of (now) 9 blocks with no evidence that any of them led to long-lasting changes of behavior.
(c) the failure, despite being an active editor for more than 15 years, to understand (or maybe "to accept") how consensus works, as reported by WhatamIdoing above based on this exchange (see another example here).
(d) the continuation of inappropriate behavior after receiving a final warning for edit warring:
