It lets people know where you stand. It may not explain why, but that gum flapping may not matter.
It doesn't really even do that.
Are you for higher taxes on the wealthy?
Higher than who? A progressive tax, yes. Just random gore the wealthy, no.
Is 250,000 a year wealthy?
Yes. Compared to 40,000 a year. Sure is.
Are you for the death penalty?
No. For two reasons: I don't think we be 100% certain that we're actually killing the right person, and I think death might be too easy for some.
Do you believe in spreading the wealth around?
That's more a phrase taken out of context, so there is no way that should ever be a yes or know question. What is meant by the person who uttered such a phrase, and what is meant by the person asking the question? That requires a lot of understanding between the parties.
Are you for gay marriage?
Yes. And why matters. How it's painted matters. The question is only good in yes and no form for a vote on the issue. Without discussion, it's really meaningless.
Do you believe Roe v Wade was a gross overreach by the SCOTUS?
Much more complicated. And something I'm much less sure.
Was Algore cheated in 2000?
No. But the resulting circus was a disgrace for both parties and the courts as a whole. We all lost something in that. Again, a yes or no is meaningless in this discourse, and would only matter if we were somehow voting to do something about it.
Did the Florida Supreme Court vastly overreach?
See above.
Did Bush lie about getting us into Iraq?
Of course he did, but it too is complicated, and unless we're voting on some action to take places, a yes and no alone is meaningless.
Did the Dems in Congress vote to send troops to war for political expediency?
Is that even what they did? Didn't congress as a whole really just pass the buck?
Did the Dems turn their backs on the troops for political expediency?
And isn't this just a stupid question? And yes, there are stupid questions.
You see, in 5 minutes I could learn more about you with Y/N questions than all the gum flapping and rationalizing of positions. Therefore they provide great insight into understanding.
No, you really couldn't. With no explanation, all you could really do is use those answers to paint any picture you want to paint. And believe me that has become the method of the day in this country. To paraphrase a fictional MLK from the Boondocks cartoon, too many today seek more to use an answer to inaccurately frame a debate or tar an opponent, and too few seek to listen to understand and consider.
