Why is such a good person as Musk, doing that? Calling for attention? https://youtu.be/Cq82Mbjsl2E Tesla CEO Elon Musk has taken a swipe at Bill Gates by tweeting an anti-vaccination cartoon. Musk posted an edited cartoon, originally created by conservative artist Ben Garrison, depicting an illustrated version of the Microsoft co-founder. Musk deleted the tweet about two hours later, after it had been shared more than 5,000 times. ...one thing are words, the other are facts: Mr. Bill (using Latinos social connotation, instead of Mr. Gates), had apported millions of dollars in research on the cure of diseases and that means vaccines too, around this Plannet Earth. Now I question: and you? ...in reference to Elon Musk. You once suggested to nuke the Moon! Is your way of thinking as productive as the way of been of Mr. Bill Gates? ...think and think twice ...now I wonder: Why some very few African American people act like that?
