Some people are just crazy.
That's not an insult. It's just the closest adjective to describe their condition.
My favorite people are "good crazy". I consider myself one of those, albeit high-functioning.
My least favorite are "bad crazy". Dangerous. Even they don't understand the malevolence they harbor or why.
You're probably among the former—to at least some degree—if you can read this post.
And yes, that's a compliment.
