I have posted my comments indicating that I would be offline after them as a courtesy to others, who might wonder why I haven't replied to them quickly or might not be doing so at all.  Not everyone checks user and talk pages to see courtesy postings about online status, etc.  Sorry that you find my attempt to be courteous to other Wikipedians "annoying".  In the past, you (and others) have not understand my comments (see the archives); as you (and others) seem to mistinterpret what I write and to read intentions in what I write that I do not have, I have suggested that you (and some of these others) not engage in these kinds of exchanges with me; I do not find them productive.
I am replying only out of courtesy and so that eventually this exchange can be archived by the automatic archiving bot.
There is no "rule" or "guideline" in Wikipedia that one must reply to every comment in one's user talk page or an article talk page.  Replying is up to one's own discretion and time constraints ("schedule"). There is no requirement that editors must spend their time editing Wikipedia; WP:POL states the opposite; that one should not be criticized for how one chooses to spend one's own time.  That is the prerogative of each of us.  How we express ourselves, as long as it is courteous, is also up to each of us.  If we want to take our time to criticize others, we need to keep in mind that we are doing so in public space and that our criticisms are being read by whoever logs on to that space.
From my own perspective, I find the comment posted above gratuitous and unnecessary.  Irrespective of that comment, I will continue to post what I consider a courtesy to others since that is how I intend it to be.  I do not intend to annoy anyone.  The guidelines for how to address other users are in Wikipedia:Etiquette, WP:NPA, and other places linked in WP:POL.  I try to follow these guidelines in what I post in Wikipedia. To assume otherwise is to violate WP:AGF.  I am posting this reply in good faith as well.   

To others who might be more interested than some in why I may not reply quickly or at all: I explain that in "N.B.", but not everyone consults a user's talk page when commenting in article talk pages, and so some may not see that explanation in "N.B." above; therefore, I have mentioned that I would be offline in some of my recent comments in talk page article(s) that I have worked hard on in the past.  I will be back offline after this reply and will not see what anyone posts here until I return to check the functioning of the achiving bot (I don't know when that will be).  I have a massive amount of work to do offline over the next two weeks, which has been delayed in getting to me (thus I've been online occasionally in the past week from time to time), but I expect to be away from Wikipedia after this reply for indefinite and extended periods of time both during and after the next two weeks as well (on an extended "wikibreak"; please see the template notice above).
