"Doug - What is the claim that all the Himalayan glaciers will be gone by 2035 or that billions of people's homes will be under water in the near future but an appeal to fear?
When class warfare is promoted and one group's political opponents (corporations, investors, the "rich", etc.) are demonized, what is that but an appeal to hatred?
When policies are put forward that are arguably unsound, contradictory, or just don't make sense, who does that appeal to but the ignorant? "
For the first, well, it's a fine line. If there is evidence that our world could change drastically, and affect millions in the process, I believe it's important to discuss that evidence, and the conclusions drawn from various camps on that evidence. When it's stated as fact [ie, you will die if you don't change your ways to the ways I want you to change them to], that's trying to win the argument through fear, I agree with you. But saying that evidence seems to suggest, based on empirical observation, that the Himalayan glaciers will be gone by 2035, and we think this is why (and we think that it's not that, but this), that's not fear based, just evidenced based, and discussions that should be had.
On the second, I view this as a bit of a conservative canard, at least as far as the class warfare bit. Pointing out that the wealth of this country continues to go to fewer and fewer individuals, and that our tax system is often regressive and should be fixed, is not promoting class warfare. I'd instead argue that the unbridled greed of a fortunate few and their 'friends' in congress do more to promote class warfare than anything else. I will, however, agree that demonizing one's opponents is an appeal to, if not hatred, at least intolerance. And it's not helpful at all.
On the third, ah, that word arguably. Whether or not a policy is unsound, contradictory or just doesn't make sense often depends on which side of the fence you graze. From my experience, there are so terribly few open minds any more. Most everyone takes a side, and any idea or policy put forth from the other side is automatically bad or unsound, not even worth considering. And that's quite sad.
In closing, I'll add that I'm not a fan of either of the two major political parties in the US. I think most of our elected representatives, from both parties, are clowns and buffoons with very little integrity, a heapin' helpin' of dishonesty and so full of hypocrisy I'm surprised they can see straight.
So, to what I gather your overall point was -- the left does it too! -- I'll agree wholeheartedly. I would hope we could agree that when either side is doing it, and they both do it often, it disgraces and dishonors our political system, and does nothing to truly solve the many problems we face today.
