(edit conflict) As to the second issue, yes, my "personal view is that the content in Giano's post is a personal attack" (a view that arguably most in the ANI thread share). The blocking policy, WP:BP, is clear that "persistently making personal attacks" may trigger a block. The policy does expect that "blocks will be made with good reasons only, based upon reviewable evidence and reasonable judgment, and that all factors that support a block are subject to independent peer review if requested", but that does imply that administrators must use their individual judgment - what you might call "my opinion" - to decide whether or not to block. In particular, the policy states that "Warning is not a prerequisite for blocking", and a fortiori, discussion is not a prerequisite for blocking. So, yes, in that sense, I may be "enforcing [my] personal opinion about what is and is not rude", but that opinion must be based on sound judgment and stand up to community review.
