Concepts and proofs are contestable in Scientific discuss and academics but the practice is usually supported by references (usually peer review, and known authorities in the discipline). I do notice some unfair downvotes just because someone is angry, perhaps just for reputation, defense of own response/answer, unfriendly habit, racism or just not yet exposed to similar line of presentation of work or facts of graduate academics, and advancement in knowledge on the topic. Though we can flag, It will be "super fair" that reasons should be supplied to downvotes and ( much better) response to contest and put right Academic concepts and methodology (and using verifiable references) for sake of contribution to knowledge rather than unproductive reputation. Thanks.
NOTE PLS: as brought to my notice, this question's formal structural construct which relates to " unfair downvotes and what to do" already has answers here: ( Downvoting for no stated reason is abusive)" and here (Why do people think downvotes need explanation? )" . Thanks.
