I think it all boils down to the "War Over Control" where some people want to control other people.

Personally I think if Islamists/gun grabbers/drug dealers/child pornographers want to destroy our way of life then they need to do it themselves -- I'm not going to do it for them by enacting draconian, broad-sweeping, and baseless laws that delegate power to people with questionable motives (all in the name of "safety").
