Dave_Mustaine is anything but an idiot, he has last two albums are themed on the up and coming oppression of America. He knows more of what's going than most other puppet artists that are obvious and even support it Its called freedom of speech, and It doesn't take Alex Jones to tell you that its days are numbered.
Dave Mustaine has signed for labels that were owned by Capitol Music Group, Warner Music Group and Sony Music Entertainment - are these not the very "Global elite corporate brainwashing entertainment machine" that you warn against? he is part of the evil elite - why do you trust him?
And maybe his problem with Obama comes more from the fact the Mustaine is strictly opposed to gay rights and Obama supports them?
Thie above avoids two important points, first of dave mustaine is not someone a rational person would listen to for coherent commentary on anything other than maybe his own right wing christian opinions.
Secondly gun sales have soared so it would have been a terrible plan... or maybe it was done by the NRA to increase gun ownership... no evidence for that but then who needs evidence
