Yes. Absolutely. 100%. While I get what you're saying, it's not on the recipient of an n-bomb to look up the person who just called them the n-word to judge their mental competency.
> “Rule are rules”… well, people in wheelchairs get a different set of rules and I’m perfectly fine sacrificing some of my own personal comfort to make accommodations.
I vehemently disagree. I can't think of any way that making accommodations for wheelchair friendliness inconveniences anyone. The doors and aisles are wider? That's great when I'm carrying a large box! Text is printed largely and in high contrast for people with vision impairments? Yay, now I can read it more easily!
I'm not saying Terry was a bad person. However, his illness caused him to say some outlandishly awful stuff to people. Why should they have to endure having those epithets hurled at them?
