PDF allows everyone, ethnicity, nationality and religion to express the opinion/observations within the norms, civility and with manners. To avoid such offenses and derailment, report the member/post immediately without quoting back or doing so and Move-On. Most of trolls, despite any flag, gets a free pass as when quoted back with same language. PDF does not believe in any discrimination. Every member has to feel his/her responsibility by reporting such matters without doing so. The one side narrative never caters the interest nor carries any weight as well as, providing an opportunity for the other side to speak its mind. Forum Rules are intact and everyone is bound to follow the same hence, found any violation, do report.
It has been observed that threads are not just destroyed due to a single member but participation of same class from everywhere while feeding the troll to grow further with strength of ill mannered posting. Any member that feeds such offender, is partly responsible for such mess even replying the troll. IMO, fair chance of speech is being practiced and it is the beauty of debate/arguments that both sides are provided with equal opportunity (despite any flags) though whosoever tries to sabotage such environment, is not welcome hence, reporting would do wonders. Silencing a voice wouldn't prove a point so to change infected feed of media, media warfare and propaganda it is must that the debate be carried with quality posting, substance and worthy analysis as counter arguments.
The fair policy is the reason that despite illogical complaints from either side, PDF is still is an interest for many, therefore, to maintain the decorum and friendly environment, Forum Rules are implemented and applies to everyone without any difference of nationality.
