Bills are not written by people on discussion boards. They are written by lobbyists, and then adopted by legislators who rarely even read the bills on which they vote.
Then perhaps you might like to campaign and vote against legislators you believe are representing your opinion so poorly? With primary elections it's far from impossible to get rid of bad candidates.
Cynicism is a free pass for bad legislators to continue operating badly. Reasoned, constructive, informed opposition is needed to get the desired outcomes.
