I think people tend to have a very narrow view of what goes on around them. And frankly, I don't think that's really a bad thing. Everyone does it. It's just a fact of life. But we have to account for it. Talking about big-picture issues doesn't work when people are focused their narrow view of the world. Even if they agree with the issue, they won't be riled up and take action. I think there's 2 takeaways to this:
First, regarding talking to the people around you: narrow your focus. Focus on things that affect them directly, or frame things in a way such that they interpret it in a way that affects them. Don't talk about concentration camps, talk about Trump retroactively rescinding birthright citizenship and how that might affect their lives (especially effective if that person happens to be an ethnic minority or is in a relationship with one). When talking about anti-immigration policies, focus on ICE arresting American citizens because they didn't look American enough. You don't have to convince people of everything, you just have to convince people of enough that they feel personally concerned.
Second, regarding yourself: it's easy to think that all Americans are similar to the people that you're with. Society is a bell curve. You don't need to shift the entire bell curve to the left to exact change. You just need to stretch it out leftward - pull the left leaning people more to the left. Trump didn't win by convincing leftists to be right-leaning, he won by convincing the right-leaning moderates into shifting right. Consider the audience and pick arguments that would be most effective against that particular audience. Be more direct toward more left-leaning people. Republican? Sow seeds of suspicion toward Trump. Moderate? Make them fear for their way of life. Left-leaning moderate? Maybe we should punish the rich. Leftist? Hell yeah socialism baby
