If you declare that someone is wrong for not sharing your definition of a word, that is a statement about dictionaries, not concepts. And while arguing over which definition you favor might be a fun way to spend an afternoon, it is very inefficient for any other purpose.
Morality is about the thriving of sentient beings.
There are in fact truths about that.
For example: Stabbing—generally a bad thing if the being is made of flesh and organs.
TGGP3 clearly does not share your definition for the word ‘moral/ethical’ otherwise he would not have made such a comment.
That would make him wrong, then.
How so?
In the direct literal sense. It wasn’t a trick question. 2 + 2 =/= 7, while we’re at it.

Which is, incidentally, why I would not recommend it happen very often. But I can’t control when people choose to be more wrong rather than less.
