TLDR: Know your friends values. What do they care about. Bitcoin is good for everyone. Do not focus on their politics and how wrong they are. Talk to them about how bitcoin relates to what they care about in the world.
There are progressive bitcoiners. It pains me to listen to them rationalize their political views in light of how bitcoin works but this is a human flaw. We will never free the world by appealing to logic and reason alone. Building a better system is the way. A system based on logic, reason, and intentional incentive structures. People are locked into their political dogma. The vast majority of people I know are not even open to questioning their views. Its pointless to argue. Better to show it by example.
