* He believes we've stagnated (see http://blog.samaltman.com/trump)
* He sees a unique opportunity to buy into politics at the highest level for a mere $1.25MM

* He found a way to get Republicans to cheer for the phrase "I'm gay"
Again, doesn't justify him... but potentially explains him.
At the end of the day, we shouldn't be surprised that a guy who's famous for asking "What's one thing you believe that no one else does?" is supporting the most contrarian candidate we've ever seen.
I didn't say we should assume he's racist, but you assumed he isn't. In fact you assumed his motivation very explicitly. I was asking how you made such an assumption.
How do you know that?
