Actually, #2 is totally accurate. The greentards on the Left don't want working solutions to an ill-defined problem. They want what they want like petulant children. Neither you, nor anybody else, can prove with any reasonable level of certainty that global temperatures are doing what they're doing because of nature versus interference by man. We don't have anywhere near enough data to do it.
Just remember, these are the same people claiming "climate change" that claimed getting rid of CFC's would fix the hole in the ozone layer at the S. Pole. Well, the hole is still there. It's as big or bigger than it has ever been, and we got rid of CFC's like they wanted.
Fool me once, shame on you. Fool me twice, shame on me.
Until the fools in the pseudo-science of "climate change" can prove their predictions correct and their modelling solid, I'm not believing them a second time, and neither should you.
As for 1, more government interference in the market won't fix the market. More government spending won't either.
Universal public healthcare is a sop to trying to fix a problem with a sledgehammer rather than with finesse.
We have quotas on immigration right now. There are guest worker programs for industries with labor shortages. They are being ignored by the current administration. As for illegal immigration, why do we need a mass of uneducated, illiterate, sickly, people with language barriers from who-knows-where pouring into the country?
Maybe we should just start handing out vouchers to parents who have school age children and let them decide rather than stick with an antiquated, Victorian, system of public education.
