My view is that you don't understand our system.
We tolerate all views and to accomodate the diversity and allow any one that can come up with support and money to participate. This is done within the loose organization of two parties. Each attracts coalitions of common agendas. The coalition with the greatest support gets nominated in the primary.
What you propose is rather backward and is practiced by the small and third world democracies where there are multiple parlimentary coalitions that must find a majority post election to rule. They continuously screw up and don't succeed very well.
In America there have been lots of efforts such as you suggest but they are mostly hot air and no substance. They always fail and they always will fail.
No, I do not tolerate all views, and this nation should not tolerate all views. There are views and causes espoused by both major parties that would have the Founding Fathers spinning in their graves. There are political parties whose very platforms run afoul of the basic, founding principles of our nation (Commies, Greens). There are movements, such as the homosexual push for special marriage and adoption rights, that are positively poisonous to the fundemental values and principles we were founded upon. This kind of diversity is not what we need, and we shouldn't tolerate it at all.
Apparently though, to your mind, as long as any of these groups can secure the most money and votes to win the primary elections, they're fine and dandy. That very thinking, sir, is what's causing our society and nation to collapse from within.
What I propose is the American Spirit in its most basic form. When a government, or a group of people, become so tyrannical as to trample our own God-given rights, it is our duty as Americans to stand up and tell those tyrants we won't take it anymore. Bloodlessly would be best, of course, but that's why the Founding Fathers protected our RKBA with the 2d Amendment.
Our two dominant party system is broken. It was once easy to differentiate between the Rats and the Pubbies, now they're Coke and Pepsi. Nowadays, who is calling for the dismantling of Social Security, Medicare, Medicaid, Americorps, Job Corps, the Departments of Energy, Education, Homeland Security, Labor, Health and Human Services, the Interior and a whole slew of otherwise un-Constitutional functions of government? No one! Hell's bells, the two dominant parties are tripping all over themselves to see who can grow government faster than the other! Meanwhile, who's throwing Border Patrol agents and Marines in jail for doing their jobs? The damn Pubbies, for cryin' out loud!
(Whew...take a breath)
I could go on, but I'll spare everyone. No, your view that I don't understand the system is dead wrong. My view is that the "system" you espouse is the very reason we're in this mess in the first place. I hate to say it, but we will be lucky if all we have coming is eight more years of a Commie Klintoon in the WH. If we don't stop tolerating so much PC and immorality/amorality, if don't stop preaching diversity and start preaching commonality (as in the common values we were founded upon), well, I hope you speak Spanish and Chinese, 'cause that your future. Mine is the motto of New Hampshire, "Live Free or Die."
