Given his past history (physical and verbal), and the things he’s said about anyone else he’s angry with, I’d lean toward him simply being looney. (Or being an a-hole, more appropriately put.)
Telling an 11-year-old — your daughter, no less — that she hasn’t got “brains” or “decency,” making extended threats that virtually anyone would interpret as physical, and closing it by repeatedly calling her — his 11-year-old daughter — a “pig”? Yeah, that requires some looney on behalf of a father.
I must plead ignorance on ALEC Baldwin’s past history.
