Yeah for someone to change their whole viewpoint takes time.
Imagine if someone was gonna try to argue that your opinion on a recent conflict is wrong. Obv if it’s that confronting you’re gone disregard that. But if he says something about it every once in a while you start to think more about and then you learn and grow. Because either you come to the conclusion your standpoint is really short sighted, or you at least appreciate their perspective.
And let me be clear: whatever you learn, it will be a good thing, because the more perspective, the more experience.
I have a friend who votes for trump and we clash heads a lot about politics, but I know I will learn so much about his viewpoint it is worth it to a certain degree, and I’m not gonna try to “convince” him, because I want him to critically think about his opinions and learn what he needs to from my perspective.
If you wanna fight racism for example, be a living example about how stupid it is and how nice it feels to know you can judge people by what they do and not what they look like. Don’t talk about, just be clear whenever the topic comes up.
