Liberalism needs to die. You can argue politics until the cows come home but you will never settle the debate in the realm of ideas. It takes the darwinian struggle to put the debate to rest. Our founding fathers understood this. They chose a limited form of government that emphasized state sovereignty precisely so that failing ideas could fail in isolation.
On a more pragmatic level, most young couples starting out simply can not afford a house in California. Are you really going to tell them to stick it out rather than a make good life for themselves in a red state?
You're calling this a liberal state, a state that since the late 70's has:
-Rolled back and limited property taxes (Prop. 13)
-Reinstated the death penalty and voted out three state supreme court justices who opposed it
-Voted to define marriage as 1 man, 1 woman (Prop. 22)
-Voted to end benefits to illegal aliens (Prop. 187)
-Voted to end bilingual education (Prop. 226)
-Imposed term limits on its officials
-Recalled a Democrat governor and replaced him with a Republican
Yeah, we do a lot of pretty liberal things too, but the point is a place headed for the rat hole like you describe wouldn't also be doing what it is doing above.
Sure, the results of the special election don't help, but that just proves what happens when your crappy campaign strategy is to shut up and take it for months while your foes lie by the millions of dollars.
I'm not going to tell couples what to do about where they live. They can stick it out here and fight, or tuck tail and run to where everything is nice and safe for their tender sensibilities and they have no fear of or need to engage in the struggle to preserve something incredible from where the battle needs them most.
I'm staying put.
California is a beautiful state. I'd rather stick it out here and fight then move to some nasty hellhole just because I won't have to fight.
