There is additional proof, from his sister's Facebook page, but I'm not sure I want to link it here because it seems rude to link his family's pages to random people. Is there a moderator here whose email address I can message with the proof?
Though Wikipedia already has such a link confirming it. I don't think you need to prove it.
Edit: Or did. I can't find it now. I was sure there was a really short page for him on Wikipedia when I looked the other day. At the moment, he only appears on their disambiguation page without a page of his own. It also shows a death year of 2018.
Taking a shot at people with whom you disagree undermines your message. What might have been thoughtful is now a diatribe based on a stereotype.
