Somehow I suspect you don't think much of such "touchy-feely" adages as "If you have nothing nice to say, don't say anything at all", but really, your original reply already made clear what you thought of the post. There's really no need to go on about it and give the rest of us "vergüenza ajena" (if I recall correctly, a Language Log post some time ago went on at length about how English had no equivalent for that term).
