That seems an unfair burden. Many laws cover complex matters and the average American cannot be expected to know the pros and cons of every bill. I like clean water, for instance, but my opinion on what that means isn't well developed enough to vote on laws on exactly what should be permitted.
Our lawmakers aren't exactly subject matter experts either. And their SMEs are probably often just lobbyists.
Maybe that's because I've always lived in a direct democracy where it's commonplace to propose or challenge new laws, and while engaging in that process does require a few hours every now and then, I've always felt that's more than worth it.
By all means, I very much support citizen led initiatives (and there have been some excellent ones), but not out of the blue as an after the fact evaluation of a law.
