Speculative fiction from decades ago, even some Disney productions, may have got some unconfortable stereotypes, and maybe productions from today will need some disclaimer about "it is not our intention to promote anticlericalism or hate speech against religious communities".
Some players may be racist or intolerant but the true D&D doesn't promote hate speech against people from real life. Before we should wonder about if Warhammer 40.000 and the xenophobes space marines are promoting totalitarism. Or we could talk about the red paladins, the antagonists from Netflix's "Cursed", or the Gilean republic from "the tale of the maid".
I say it again, and time after time if it is necessary: reporting hate speech is not enough, we have to use speculative fiction to teach and to promote the respect for the human dignity, the core of our rights as citizens and people. We have not only to stop the hate, but making efforts for a mutual trust between everbody.
* Lovecraft had got predjudices, but this usually is forgotten.
* Should we report manwha fantasy if this too human-centric and not enough inclusive with fantasy races?
* Has anybody complained about the darkspawns from the videogames "Dragon Age"? Then why complains about Tolkien's orcs or D&D gnolls?
* Take care with your words. If the other side suspects you are trying to manipulatin emotionally appealling the feeling of guilty and shame then they will not want to keep hearing you. Be absertive and diplomatic, and try to get their trust.
* Today Disney's "our dinosaur is missing" may be tagged as sinophobic, but when I watched it being a child my respect for Chinese people was not worse, maybe thanks "Kung Fu" serie, a door what helped me to know more about Chinese culture. Sometimes I can say some horrible things against the current Chinese goverment, but this doesn't mean I despise China, I don't at all. I can talk about the "rotten appels" or the "black sheeps" but being respectful with the rest of the group.
* I am afraid 2021 will be the year of a new Satanic panic, and this will be worse. The good new is teorically the RPG franchises will not affected, or at least not before videogames with lot of gore and extreme violence (Mortal Kombat, Doom Eternal..).
