I disagree, and I also don't care. I really despise this sort language policing, it is clear what my message was.
The only group of people I disparaged are Tesla investors, deservingly so.
Other types of mentally impaired people have my full sympathy, and that includes charity.
The thing about using slurs is when you respond with "but [group] deserved it!" you've implied that you're happy to use it against someone if you subjectively believe they're "deserving" and that the term should be received negatively
