The longer I've followed the news, the more of it reads like nonsense to me. It's mostly just a heap of non-newsworthy stuff presented as if it actually matters.
It's the same with political debate, really. It doesn't really matter what arguments are presented, because I've heard most of them before, and they didn't convince me the first time either.
When you boil down politics to its essentials, it's all just a big game of justifying various feelings. You present an argument, but it's just a decoy for your true feelings. Defeating the decoy doesn't change those feelings; it merely forces the person to find a new decoy argument for the same feelings that didn't go away. The only way of resolving such conflicts is to vote according to your conviction, or if that isn't enough for you, go to war over it.
In my opinion, personal experiences can change political convictions. If you're anti-gay, discovering that your beloved son is gay might trigger a change of heart. If you can't stand black people, positive experiences with black people might make you feel otherwise. Living in a properly functioning social democracy might make you change your views on socialism.
Arguing on the Internet is usually a rather futile exercise. When I share things on here, they're more like conclusions than the beginning of a debate. I have reached that stage of life where I'm fairly settled, perhaps even a bit stubborn, in my ways.
