Where's your "factual basis" for such assertions?
> Regarding your specific point about using recent context to inform political opinions, if you spend any amount of time listening to the opinions of people online you'll find that not only do they fail to accurately recall past events, but they don't bother to research what actually happened, and when they do they fail at anything but the most superficial political analysis.
1) People regularly online are a rather specific group
2) People sharing their opinions online are a very specific group
3) Basing your views on society at large on opinions of those groups is a risky strategy, especially given how easy it has become to spread propaganda online
Anyway as for my optimism, it's based on actually interacting with people directly. Having discussions with them. Talking to them about what they believe, and why. They're usually a lot more complex and intelligent than those various descriptors used above.
