I think there has been a misunderstanding. My comment about the broad range of topics are permitted and the limited types of things that are disallowed in post #20 was a general description, not specific to any given warning. I didn’t make any connection between the two warnings you mentioned in the OP and your follow up paragraph’s general description of being constrained about topics for discussion.
My reference to hate speech being forbidden wasn’t related to the two warnings you mentioned.
Here is the warning that manson earned:
The ideas that manson wanted to discuss would probably be fine in GD, i.e. the impact of the behavior of victims in their victimization. But that’s not ATMB material. I attempted to head this off by closing the thread that was going off the rails. Manson does have a pattern of the one line rapid fire question type posting, and IIRC it typically happens in the evening when he has previously said alcohol may be involved. With this background in mind, and given his comments seemed to be escalating as a way to torque others off, especially because it was analogous to the behavior that SamuelA was warned for, I closed the thread in hopes that he would take that as ending that line of discussion. He seemed intent on continuing, even after being told that he would have most likely earned a warning if he continued, and then he continued. Kind of open and shut there.
I’m not familiar with what that is beyond what I just looked up on the wiki page. That’d fine as a debate topic as far as I can see.
Also fine 
You’d have to have the discussion in English though.
