Sun, it is very easy to cast aspersions but it would be nice if you could exercise some magnanimity and thoughtfulness while doing so. It is amusing to note how you had effortlessly concluded that the editors are partial. Just think why we should be partial to anyone? It may be noted for prudence and posterity that we, the editors, have no special liking for any member. Let this be etched in your mind because, if I am not mistaken, this is not the first time that you are raising such an allegation.
I am not here to justify the editors or to try and bring clarity to your thought process but would certainly like to say why your thread was locked and the other one was not. Without discarding the possibility of overlooking (quite possible), let me give you another reason. Your thread was to remember Smt Indira Gandhi on her birth anniversary and the thread would naturally lose significance once the day is over. The thread on International Men's Day had a few more details about the day and it is a topic that can be generally discussed. In such cases we generally allow such threads to remain open for one or two additional days. Otherwise, threads on special days are locked the next day unless we miss it out.
As a rejoinder, I would like to suggest members to avoid coming up with commemoration threads unless you have some details to add for discussion.
