Legislative functionality isn't the same as country functionality. Are you trying to equate the two?
As for the bolded, who in blazes suggested doing that?
And you're quite correct in your last paragraph. The system indeed works when that happens. The problem is that you've allowed radicals to contaminate the right, with no counterweight in the left. Without that, what, pray tell, do you think happens? Look at how economic rethoric is handled in your country. That's what fucking happens.
And that, my friend, is not something that the SC will eventually solve for you, no matter how many seats you get up there.
How do you plan to tackle that?
