Mr. Hawking,
With all due respect, you are on the wrong side of history, and on the wrong side of humanity.
It's difficult to not be cast as the bully when one counters a technically brilliant man in a wheelchair. But, you are correct.
Mr. Hawking, for all of his knowledge and specialized intelligence is woefully incapable of making a call on this issue.
I recently checked out a copy of the SFWA Grand Masters Vol 2. and was reminded of how many of the writers I once enjoyed reading, were and are unrepentant lefty nutballs.
Asimov, Clarke, Bester, Aldiss, Dick, etc. are great creative minds but man...what idiots when it comes to right and wrong in the real world.
