😊🙏 I do not know what to say because what is written is not only unethical but appears as a parochial conduct. Writing is a matter of right. Whoever he or she may be. Writing to a friend or family member is exclusive within them. However writing in Public requires etiquette, poised tendency, analysis and sifting the material carefully. Write up will defend the writer if the writing can defend one. Suppose a probable after tiring oneself, (which is not a glory to any one nor demanded out of him as aqualified) publishes 1+1=5; of which he might have been convinced, since it is his learning and the matter of right cognisance,within the ambits of cells within; but the answer 5 is wrong; in family and close friend one may walk off for the obvious reasons; but public is a large forum, where the interpretations and the analysis are too many ,where even the right materials are debatable; if so wrong material will be thrashed out only. KSS heart is adored but not his mind to mind the errors. Whosoever one may be, let there be thoughts in the right mode. As KSS pleaded, he has all the rights to defend the hard worker as well as rightly oppose the criticism material but not the critic. Important thing is that one shall not impose on oneself, or feel predominantly, that he alone is the master of english etc (many material observations) where one's finger when indexed, must see the three fingers do not see , in the opposite direction viz oneself. Thank you sir. Seivana tirunda sei ; solbavai vedamanaal, solvadhum vedamagum. Thank you KR IRS 08 12 22
