My two cents: you're not allowed to write an in-depth description of what a serrated knife can do to another person, in specific areas of their anatomy, followed by a vivid description of how you felt when performing said task on someone. This is in, despite the fact, that we have several talented writers who could go into such vivid detail about performing said actions in character. The reason why nobody writes such descriptive writing on this board is because we're all agreed that nobody wants to read that, and from a personal point of view, nobody wants the stigma of being seen as, we Englishmen like to say, "a nutter".
No. Such an "attack" would come down to a few short words of, "I am trying to stab you with this knife. What are you going to do about it?" and that is just about as much description is needed for such an important function of roleplay. People do write about their characters attacking someone else's character with a weapon, such as a knife, all the time and it never crosses that uncomfortable line because we understand the intent isn't to disturb or gross out someone OOC, it's just a function of roleplaying.
Conversely, this sentiment can be applied to a whole host of things that can equally cross into that disturbing, and quite frankly, cringe type of roleplaying that we have all seen, and experienced in other boards or communities. We've all been doing this a long time and we've all met that one guy who likes to cross the line.
As this applies to this particular thread to the banning and outright censorship of racism, and homophobia, my understanding and interpretation of this ruling is very simple. In the same way that nobody wants to read a 1K word essay of someone's character flaying another's character in some dodgy private thread we also don't want to read the same descriptive writing that outlines a characters racist or homophobic views for the exact same reason.
It's cringe, disgusting and, even if it were "allowed" would amount to people not wanting to write with you anyway.
If nothing else gets through to the people debating this then I can summarize my thoughts with this: the guy who owns the website has told you that he doesn't want this written here. That's it. He isn't going to change his mind about it. He has said it more than enough times throughout this thread telling you so. At this point further discussion seems trivial, reads as egotistical (you don't want to lose an argument) or you appear to be arguing in bad faith to make Tefka look bad.
