While I'm not familiar with Spidey's posting history that is referenced, can we get some clarification here? Is it only Spidey that isn't "allowed" to use the term in question? Is it only Spidey in the context of this thread? Is it only him in the context of this case? Is it only him in the context of a specific race?
Are we all not "allowed" to use the term in question? Are we only forbidden from assigning the term to this case? Are specific races exempt from being labeled this term or is it a blanket banning of the word?
Again, while I am not familiar with the other things Spidey has posted, the term in question 100% fits the person he assigns it to. As others have already pointed out, your contention that the term "is a now widely recognized code word for blacks" seems to be wrong. You may mean that the way Spidey uses it is recognized, but you are not clear about that. "widely recognized" implies that equating a specific race with the term in question extends well beyond Spidey.
If we could get a list of what normal definitions of words that we are "allowed" to use with what races, sexes, genders, etc. that would really help clear up some confusion! The obvious racial slurs would, of course, be included (understandably). But, if we can get a sticky with what innocuous terms we are not "allowed" to use in reference to specific races, I think we could have a much more appropriate discussion!
I'm right behind you, this is confusing.
It appears that the real issue is Spidey, and the belief that he's a raciest. Rather than try and control what he thinks, why not just ban him? We don't need the pretense of "fairness", just say you don't like him and show him the door, it's been done before. If it really is the word "thug" that is at issue, we will be needing documentation on allowable words. It's unreasonable to expect us to know what words have been redefined and what that new definition is.
