On AOC it's sort of dumb shyt for him to get on her ass about. She said that there are humanitarian issues in the increasing violence in the occupation of Palestine, and there ARE humanitarian issues in the increasing violence in the occupation of Palestine. She didn't say anything wrong.
It's true that she doesn't know how to answer questions like a politician yet. There are dozens of issues that 90% of politicians don't have "depth of knowledge" about. You go up to a random House candidate from anywhere in the world and ask them about climate change or net neutrality or the conflict in Yemen or the repercussions of the Farm Bill or crime rates on the border, you'll hit something they know nothing about very quickly. They just know how to bs their way through the answer better than she does. That doesn't make them better at their actual job. She'll learn how to frame her talking points around her knowledge soon enough.
The other video is fire though.
