There is a huge difference. Martha Burke is a wacko, so it would be safe to assume that any movie she did would be wacko. You are saying that because Mel's dad is wakcy, that therefore Mel is wacky, which is a decidingly prejudicial and un-american way of looking at the world, especially for someone who purports to be concerned about a movie being judgemental.
No, I'm saying that because Mel's dad is wacky, and cites his bizarre religious beliefs to support his wackiness, AND Mel responds to his dad's religiously-based wackiness by paying to build a "not open to the public" church for the group that dad is wacky about, that therefore Mel is wacky.
If your dad belongs to Matt Hale's World Church of the Creator, that doesn't make YOU wacky. But if you proceed to finance the building of a church or compound or whatever for the World Church of the Creator, then I have no problem writing you off as wacky too.
