There is nothing criminal in creating, using and sharing those mods (as hateful as they are), the modder could have simply said he did it because he felt like it, but the mediaval theming justification is really stupid and inflammatory.
The community reaction is very counterproductive, they have only succeeded in making the mod very visible now. And nexusmods as usual accepting all kinds of horrible mods but censoring only according to drama. All badly here.
