What a mess I've made 
Sigh... this was all entirely my fault. My only "defence" is that it's been over half a year since I was last blocked and I slipped up - yeah, it's not much of one at all (hence the quotation marks).

User:Guy Macon, I should have stopped with the template warnings immediately after you made it clear that you did not appreciate the first one (which was indeed issued in good faith, even if it did not seem like it to you - but I suppose that doesn't really matter much at this point). Issuing another warning for an edit you made to your own talk page was particularly ridiculous on my part.

User:Thomas.W, I should have heeded your warnings instead of mentioning possible retaliation. Not much more I can say about that.

User:DangerousPanda, I shouldn't have written the comment above (which I've now struck out). Your well-timed block likely saved me from a formal report (and a possible community ban, given my sanction history).

Please let me know what you all think of this (particularly since I'd like to be sure we're now on the same page before filing a formal unblock request). Thank you.
