These discussions are really interesting to me (I lurk a lot) but tend to always just deteriorate into tribal sniping from the trenches. Perhaps because the initial question, whether intended or not, will always be interpreted as an attack on the group that is being asked. It would be more interesting to see self-critisism from either “side”.
I’m neither liberal or conservative, and those american labels would largely be pointless in the context of my culture, but I see simmilar problems from the group I associate with. I was a politician for 6 years and started out somewhat in the political trenches, but as I learned and evolved I became less and less partisan. Today I am ashamed at some of the opinions I once held, not so long ago.
My party is the Green party (third largest of eight) and we have a problem very simmilar to the one described in the OP. A lot of greens or enviromentalists tend to assume that political groups that don’t agree with them are, for lack of a better word, evil. I’ve often heard members of my own party say things like “X wants to destroy the enviroment”. That is of course an easy, and perhaps attractive answer, but it also assumes that a rather big group are out to destroy or hurt others. Basically that other people are psychopaths.
After spending 6 years talking to and working with politicians from other parties, it gets pretty hard to sustain that notion. Instead, I think you will come to find that even though there is ignorance and egoism in the world, and the world of politics being no exception, the vast majority of people simply want to do what is best based on their values and their understanding of things.
At the very fringe of ideas and movements are people who simply seem to have fallen off the trail. Whether it is some christian nutjob who’s interpreted “Love thy neighbour” as “God hates fags (and so should you!)” or someone believing that the white race is under attack from muslims/blacks/jews/asians. And even they could probably be assumed to have what can be described as “good intentions” at heart. If I believed I was part of a group (white people) that was being targetted by another group (non-white muslims), I might come to the same conclusion as them. But I don’t, so I won’t. The road to hell really is paved with good intentions.
I also find that it is much more constructive and successful to assume that other people are honest and have good intentions. That makes it possible to communicate with them, which will improve both sides understanding of eachother and perhaps even find common ground. Not the extremists or fundamentalists perhaps, but the vast majority of people don’t fall into that group.
As I grow older I’ve found partisanship to become more and more off putting. I can understand it in younger people who have yet to create a more nuanced world view for themself, from people with more experience, I find it hard to respect it. As a politician, I always try to find out what the right thing is and then try to do it. I assume that most people do the same, even though we can come to different conclusions. I also accept that in every given case, I can be horribly wrong, this also being based on experience.
I assume that most conservatives want to lower taxes because they believe government spending is wasteful, incompetent or counter productive. Because that is the reasons they tend to give. I also have to acknowledge that they are right in some cases. Some government spendin is wasteful, incompetent and counter productive. And I agree that the wasteful, incompetent or counter productive spending should stop.
I assume that american liberals want to raise taxes because they believe that some resources can be spent for greater benefit by the government. And I acknowledge that they’re also right in some cases.
I would support shutting down programs that are wasteful or counter productive and using the surplus as a tax credit. I would also support raising a tax on something harmful and spending it on something useful like education. And I think there would be a big majority for it in any parliament where people voted according to their beliefs and conscience rather than according to what partisanship dictates.
If you actually do believe that “liberals” just want to spend tax money for spendings own sake, your understanding of other peoples motivations has a gap and, you’re basically falling into a trap set by partisans. Partisans are the ones who benefit from demonising their opponents, but everyone else just ends up losing.
