I don't know much about this Youtuber, but his video is the only one I can find that has the extended speech Bernie gave to a class in 2003. So ignore that guy if you want to... but the Bernie speech...
About how the Republican party gets people to divide, and get people to vote against their interest (health care, education, living wage) and as Bernie has said, their goal is to try to get people to not fall into that...and bring everyone together to first get these basic things in place... then imo, people might see more clearly about not caring/hating about what others choose to do with their lives. There will always be pieces of shit out there, but imo there are more good people out there than bad.... some are just stupid and gullible. Need to wake their asses up.
