If an idea is bad enough to be worth tabling, finding a Senator to second the motion should be trivial. Lone dissent isn't being stopped; vote nay to your heart's content. But don't muck up Senate business by flinging out motions to table legislation for no other reason than you dislike it like a machine gun.
Two things. I totally agree that motions to table should not be used just because you have a personality disagreement. That being said, I do not agree that getting a second will be that easy. What if there will a bill that I fundamentally thought was wrong, but the rest of the Senate just did not care or disagreed with me. By being able to slow down the debate by a motion to table I take a stand. We don't have the filibuster. Sometimes voting nay is just not enough.
