Yeah, i've seen how social media polarizes people by dragging them further into the echo chamber. They started out pretty moderate but slowly get dragged further into their own echo chambers, whether on the left or the right.

As for the presidents, yeah they've all been pretty bad in their own ways. Which i can see why folks tend to say, "they're all the same". Some truth in that, but they're bad in different ways. Or as they say in Thailand, "same same but different".
