You took it much farther than that. That rule is meant for people to have a discussion with each other. One person makes an argument, the other is supposed to criticize the argument and have a discussion. That rule has nothing to do with racial slurs and insulting groups or specific people outside each specific conversation.

Do you really have autism?

You don't seem capable of understanding intent. u/Graphenium called someone a "fucking Mongoloid" and you didn't see that as insulting. That's very dense lol. u/Graphenium also tried to tell you there was a difference between saying the word kike is used as an insult, versus using it to insult someone. You didn't understand that and viewed them the same.
