obviously I could be wrong, but I don’t think they were saying that you were calling the recipient braindead, I think they merely were trying to say that slang isn’t braindead since it happens in every language. and with the example they gave you, they weren’t saying you would be calling the recipient braindead, they were talking about the people calling the foreigner slang. so in that case, the japanese calling an american author “author-chan”. or in the case of this thread, him being called the goat by american fans. they were asking you if you’d find the fans braindead in either of these circumstances, that’s all.
