The problem is who are you listening to.

If you talk about anything in a public place, say in a pub, it won't take long to hear a differing opinion.

We've worked so hard to create closed communities on the Internet, that you're not exposed to opposite ideas unless you work hard at looking outside your bubble. Social media with its very smart recommendation algos will try to keep you firmly in your echo chamber.

Yeah, you can listen on the Internet too, but you often only hear the choir.
