Ok, fair enough. By surrounding myself with men holding guns - do you mean law enforcement and military? In that case I don't see a disconnect between supporting issuing firearms in a highly regulated way to law enforcement, and not supporting widespread use among a population.

I don't think your Bill Gates analogy makes any sense at all. His work in his foundation, and the expertise he has access to, seems pretty removed from the size of house he chooses to live in. Is your argument that he needs a certain moral justification for warning about climate change? Or that his immense wealth disqualifies him from discussing science?
