Both! We all need to understand each other better, and off of the internet.
For example, someone wanting others to act according to their religion.
I spent decades with my parents, but there’s nothing to “understand”. They speak a different language (even though we have the ability to use the same words) and live in a different world than me.
If we can think about 5% of the population who simply have different life situations and backgrounds having a better appreciation for why they think what they do, and those 5% become less extreme and more understanding of compromising for the benefit of others, then you've just changed society completely.
