Actually my comment is perfecly in line with the rule #2. To my knowledge, Musk is not part of this community and as a public creature, does not deserve the same level protection as you or I do. 

I do not thing, it is necessary to support the claim about him being a liar. That is a well documented fact. But just in case he is going to join this forum, I am going to make a research on Musk being a sociopath.
