When Leo lives in a mud hut, no technology, no private transport, and petroleum based products, I might listen to him for a few seconds.
If he was a true believer his yacht would be powers by sail, he would ditch his cars for public transportation, he’d power his house completely with solar, and he’d share his mansions with hundreds of Syrian refugees.
Since he won’t do the right thing, he should be disqualified from making movies.
