Crazy is never used with compassion???? What about "crazy in love." What about "crazy about you?" Here is the definition of the word crazy. Look at definition #2. We can't say those things anymore? You're crazy! I guess this means we can say lunatic anymore, or unhinged or mad as a hatter. Or mad, for that matter. We can't say "you've gone mad!" when our spouse says he's going to buy a Ferrari. You know what...go away.
