Well, you probably voted in a congressman who voted in favour of this... And while there is a vocal segment of a population who might oppose it, there also plenty of comments in this very thread who support it. How do you know this isn't an enactment of the popular will here?
Apparently there are 150 million users in the US. If even a small part of the non-users oppose a ban, that's about half the population (especially since we can exclude small children).
