Does Facebook make it harder for people with different political views to get along?
Politics is about making other people do what you think is right. It's just like forcing your religion on someone except that somehow if there's not a God involved it's considered to be morally acceptable. It's the worst form of blind faith in the face of evidence to the contrary, and it's used to justify tyranny.
I really disagree with this assertion that politics is all about dominance. In skipping directly to tyranny you fail to see the positive aspects of debate and personal influence - is it bad to try to make someone see something different? Are people incapable of changing their opinions with time and wisdom? Are you removing someone's choice by having a conversation with them?
A problem happens when both sides become intractable on issues. What you're really talking about is what we've got today, incredibly polarized politics, a political system rigged to extremes (largely due to gerrymandering), with few moderates and quite a few people trying to bash each other over the head about ideas.
The problem I struggle with is when I see that an idea is bad, and the data suggests it's bad, and yet it's somehow subject for debate. Economics and taxation is somewhat debatable (to a degree). What isn't? Well, global warming denial, creationism, anti-vaccination bullsh*t. People who think, in a world where water in certain places is becoming increasingly scarce, that we should potentially pollute the water supply without some rigorous studies.
I think a lot of people go to Facebook to see pictures of babies and cat pics and impersonally catch up with friends and maybe find something funny or like what someone's up to. I like Facebook for that reason, in other words it's a positive source for me. I don't go to Facebook to see a friend of mine talking about putting landmines in his yard because there were some recent breakins (yes that happened and no i dont think he was joking). I try really hard not to push my political agenda, especially as much of some of my friends. But when I find something politically offensive in its utter awfulness, something most people wouldn't hear about, or about a candidate I like that maybe not everyone knows about, I post it, to inform those around me.
It's not about dominating friends, it's about informing them. People can come to their own conclusions, everyone has their own life history, and they can disagree with me if they want. But I don't think it's evil to try to influence someone or ask questions about the reasons they feel one way or another. And I rarely push, except perhaps with my parents, because they are quite intelligent and yet my dad has listened to Rush Limbaugh for far too long and my mom is a single-issue voter.
